Can CCTV Systems Help Crisis Management in Mass Shootings?

Tuesday, May 22nd, 2018

As school and mass shootings become more prevalent in today’s society, the question of “How do we prevent this?” Can CCTV Systems Help Crisis Management in Mass Shootings?is on everyone’s mind. While gun control is the first topic people tend to address when discussing these acts of terror, there is another side to the story that may aide in minimizing the total lives lost in these situations sooner than a gun control reform can. One of the most important purposes of Closed Circuit Television (CCTV) video recordings is to secure a predetermined area using video cameras connected to a video recorder, which in turn creates the video surveillance footage (evidence). By using modern technology to allow 911 dispatchers access to these surveillance cameras in emergency situations, we would be allowing the dispatchers to give the first responders accurate, real-time information.

 

Can CCTV Systems Help Crisis Management in Mass Shootings?

So, what can we do? Yes, there are changes that need to be made in not only our society, but in the world as a whole. But, what can we do right now to minimize the total amount of lives lost when the next mass shooting takes place? What can we do to catch these shooters before more damage is caused? How can we aid first responders and investigators in completing their jobs to the best of their abilities with the best resources possible? In short, we use modern technology to monitor and take control of the situation efficiently and accurately.

 

History of Mass Shootings

While mass shootings are becoming more frequent (an average of 7 mass shootiCan CCTV Systems Help Crisis Management in Mass Shootings?ngs a week in 2017, CNN), they are not new to our culture. The FBI defines a “mass murder” as 4 or more victims in a single incident. The first heavily recorded United States mass murder occurred in September of 1949. Howard Unruh took the lives of 13 people and injured 3 more in the neighborhood of Cramer Hill in Camden, New Jersey. Since that fateful day, the United States has become the country with one of the highest mass shooting rates. Between 1966 and 2018, there have been 150 mass shootings totaling in 1,077 lives lost. Prior to the 1966 shooting at the University of Texas where 18 lives were lost and 30 people were injured, there were 25 mass shootings from the year 1910. Little is known about these early 20th century killings. Twelve of the deadliest shootings have occurred since 2000, with the deadliest occurring just last year in Las Vegas, Nevada where 58 lives were lost and 500 people were injured at the Route 91 Harvest Festival.

 

CCTV and Modern Technology

CCTV surveillance became widely available in the 1970s. There are an estimated 30 million surveillance cameras in the United States. In 2009, Chicago became the “most watched city in the nation” when it linked its estimated 10,000 surveillance cameras with their 911 dispatch center. When a call to 911 comes in, a dispatcher can view a live video of the crime scene as long as it is within 150 feet of a surveillance camera. In the years since Chicago took this initiative, several cities and school districts have followed suit. In 2011, Atlanta, Georgia police began monitoring 100 of the cities surveillance cameras. Atlanta Public Schools gave access to their surveillance cameras to 911 dispatchers in 2014. In 2013, Howard County, Maryland also linked their schools surveillance systems with 911 dispatchers. Near our lab in Rochester Hills, MI, Macomb County is in the process of allowing the Macomb County’s Communications and Technology Center, also known as COMTEC, to gain access to the surveillance systems of all 21 of its school districts.

How does this help inCan CCTV Systems Help Crisis Management in Mass Shootings? the event of a mass shooting? By 911 dispatchers having access to live surveillance footage, they are able to provide first responders with accurate and efficient information. This will then allow the first responders to draft a “plan of attack” that will quickly eliminate the threat so more lives can be saved. Often, in the midst of a mass shooting, 911 dispatchers receive multiple calls with misinformation. Calls stating multiple shooters are present, the location of the shooter that is not accurate, and even that the shooter has left the premises when they in fact have not. With this technology, the dispatcher will be able to quickly see what information received via inbound calls is accurate and what is not.

Surveillance footage is not only helpful during the event, but during the investigation as well. Often, after these tragedies, questions and stories arise of what exactly happened. This is when both CCTV footage and Good Samaritan footage play an integral role. Even if the footage is garbled, pixelated, or otherwise unclear, audio and video forensic experts can enhance the footage so the truth of what transpired can be revealed.

 

So, what can you do?

Talk to your schools principals, district superintendents, local law enforcement, city and state officials, neCan CCTV Systems Help Crisis Management in Mass Shootings?ws outlets, local business and neighbors. Educate them about the importance of CCTV technology and how it can help in emergency situations. Educate yourself on what steps to take if you or a loved one find yourselves in the midst of a mass shooting. Get involved in discussions, don’t sit on the sidelines. Express the importance of alternative solutions to the gun control law regulations and/or political arguments. The solutions expressed in this article are simple to understand and easy to express from the lay persons perspective. You may even find yourself having a conversation with an expert that would find this information valuable.

The Importance of Establishing a Chain of Custody for Audio/Video Evidence

Friday, February 19th, 2016

The Importance of Establishing a Chain of Custody for Audio/Video EvidenceEstablishing a chain of custody for audio and video evidence is the first step in any audio or video forensic investigation. This includes audio/video forensic enhancement, audio/video authentication. Where did the evidence come from? Who created the recording that is being entered into evidence?

A chain of custody is the documentation of who did what to evidence and when was it done. A chain of custody includes people, dates, places, activity and the recording of that information to establish the chain of custody. What has been done since the evidence was created? The chain of custody refers to both digital and analogue audio or video evidence.

The chain of custody for a piece of evidence is important to the legal community because it adds credibility to the audio/video evidence. However, it is common for law enforcement and others in the legal community to often overlook establishing a chain for audio/video evidence. It’s not because of neglect but more often due to lack of training or understanding the importance of the process.

Unfortunately, audio/video recordings are sometimes entered into evidence without documenting the evidence recovery process. When this is the case, if both parties agree that the evidence is acceptable, and tamper free, the audio/video recording is established as the ‘original’ and the chain of custody begins there.

An audio/video chain of custody begins with the evidence recovery process. This is the process of forensically removing the original audio/video recording from the recorder that created it. Based on our experience at Primeau Forensics, once both parties in a criminal or civil litigation agree on an original, they request each side’s forensic expert to establish a protocol for recovering the audio/video evidence. This protocol is written step by step instructions created by one of the experts, then negotiated and or modified and revised until the protocol is established.

Over the last 32 years practicing as lead expert at Primeau Forensics, Ed Primeau has worked with evidence recordings from client lawyers who received recordings from the police. Whenever evidence is not retrieved personally, the police reports, depositions, and other court documents that accompany the evidence must be carefully read to understand how it was acquired. This paper trail must establish a timeline; a chronological listing that accounts for the recovery, custody, transfer and storage of the evidence because the lack of an established chain of custody can easily overturn a conviction on appeal.

Ronald Johnson and Laquan McDonald – WGN9 Chicago Interview

Tuesday, December 8th, 2015

There are two Chicago Police Department shooting videos that have been in the news lately, Laquan McDonald and Ronald Johnson.

On November 24, 2015, police video that captured the shooting of Laquan McDonald in Chicago, Illinois was released to the public, almost 13 months after the incident took place. There has been a public outcry regarding not only the death of McDonald, but also the videos themselves.

Ronald Johnson was shot and killed by police officers in October of 2014 while fleeing into a Chicago public park. It is debated whether Johnson was armed or not. Over a year later, video footage was finally released after months of Johnson’s family pushing for the footage to be made public.

In an interview this morning on WGN Chicago, our lead audio video forensic expert Ed Primeau explained the importance of video in both cases. He also discusses the low quality of video that has been presented to the public, as well as the role of a video forensic expert.

Forensic Audio Enhancement -Equalization

Wednesday, July 1st, 2015

Forensic Audio Enhancement -EqualizationEqualizers can be one of the most important tools to any audio engineer, and especially an Audio Forensic Expert. There are many different types of equalizers with different capabilities, but the core functions are always the same. Equalizers allow the user to increase or decrease the level of different frequency ranges or ‘frequency bands.’ Each frequency band is typically marked by its center frequency, while the width of the band will vary between different equalizers. Some equalizers even allow the frequency band and the width to be adjusted.

Having these controls at your disposal when performing an audio enhancement is crucial. Noise and other extraneous frequency content is usually the biggest issue with audio recordings. Equalizers and filters offer the ability to remove narrow ranges of frequencies so that these noises can, for the most part, be removed from the recording while leaving other frequencies untouched.

When using an equalizer, it’s important to be careful boosting and cutting different ranges. Sometimes removing a certain noise may sound helpful at first, but there could also be a lot of important voice content in the same range. Making the proper adjustments with an equalizer requires both experience with the equipment, critical listening skills, and a lot of trial and error. The more time you spend working with audio and equalizers, the more familiar you will become with different frequency ranges and how to best go about improving the quality of different recordings.

Now listen in with Audio and Video Forensic Expert Ed Primeau as he discusses the use of equalizers in forensic audio enhancements.

20: Body-worn Cameras with Sgt. Bill Tilson

Monday, April 27th, 2015

20: Body-worn Cameras with Sgt. Bill TilsonSgt. Bill Tilson is a police officer with the Coeur d’Alene Police Department in Coeur d’Alene, Idaho. He has been working in the department since September 2002 and began working with body-worn cameras in 2012 when the department began issuing them to officers.

The Importance of Forensic Transcription

Monday, March 2nd, 2015

The Importance of Forensic TranscriptionOver the last 31 years as Audio/Video Forensic Experts, Primeau Forensics has developed a tool to help litigators better hear and comprehend poor quality audio recordings that are to be used in court. We are very good at audio enhancement and helping our clients know the best method of audio playback in the courtroom so everyone can hear the audio recording being played during the litigation. In hard to hear situations, a forensic transcript, signed by an audio forensic expert can be invaluable.

A forensic transcript usually begins with forensic audio enhancement which is the process of using various software programs and expert filtering to remove the unwanted sounds and increase the volume and intelligibility of the wanted sounds which are usually conversations. Background noise includes noisy furnaces, air conditioners, buzzes and hums, traffic and wind. Once the recording has been enhanced, the forensic expert uses a combination of studio grade speakers, computer speakers, headphones and ear buds to comprehend and transcribe the conversation.

A forensic transcript is a signed and declared ‘under the pains and penalties of perjury’ document of a conversation that occurred in a hard to hear recording. Even after a digital recording has been processed for audio forensic enhancement, it may be difficult to hear the entire conversation. A forensic transcript is prepared by an audio forensic expert using critical listening skills, the same expertise used for voice identification and speaker recognition. Then when the enhanced digital audio recording is played in court, the written transcript can be followed during the playback of the enhanced audio recording so everyone in can understand what is being said.

The forensic transcript can also be notarized which in a sense certifies it as ‘true and accurate beyond a reasonable degree of scientific certainty’. Each forensic transcript assignment we complete at Primeau Forensics is quoted based on the amount of audio enhancement that is required for the audio recording restoration and time it will take to listen and document the words spoken in the recorded conversation.

Forensic transcription is not limited to audio recordings. Primeau Forensics has transcribed video recordings as well. We load the video recording into our forensic computer and remove the audio track. Once the audio has been enhanced, we post the clean restored audio back onto the video. Now we have a video enhancement to help with the litigation. In some cases, we have also added the words from the forensic transcript onto the screen to read as the video is playing. One such time we used this technology was when we restored and transcribed the Air Force One audio recordings the day John F Kennedy (JFK) was assassinated. See sample of this technology below:

18: Creating Video Work Product as an Audio Video Forensic Expert

Friday, February 27th, 2015

18: Creating Video Work Product as an Audio Video Forensic ExpertVideo work product is a way to document forensic investigations, like evidence recovery, for reference at a later date. Processes and procedures are documented using a video camera by a forensic expert during a forensic investigation for future use. I have referred back to my video work product many times during the course of a case when I have questions later in the evolution of the case. There are a few different digital video recording platforms that I use when creating ‘video work product’. Each one of these types of systems serves a certain purpose in assisting with a forensic investigation as well as the investigative process.

I personally use the VIEVU LE2 and LE3 body worn cameras. My main use for this body camera in my investigations is recording my forensic process in the field. This includes retrieving evidence from different systems so I can review the video later and include in my report to support the authenticity of my work product and any evidence used in the case.

Another type of digital video camera that I use to produce video recordings is a HDSLR photography camera. In some investigations, a single video recorded perspective may not be sufficient to display the forensic process or document the events. Having another high quality camera with flexibility of perspectives and interchangeable lenses can capture aspects of my investigation that body worn cameras cannot.

Video evidence produced by CCTV systems can help solve crime, as well as reproduce accidents and disasters as they occurred for play back in many different settings. A significant use a video forensic expert has when recording video from a CCTV system is to create an exemplar. This recording is used as a comparison file to the original evidence to help determine the authenticity of the original evidence.

It is a best practice of ours at Primeau Forensics to video record many forensic investigations like the exemplar creation process and evidence recovery so if anyone has any questions during the life of the case, this video work product can be referenced.

Now listen in with Audio and Video Forensic Expert Ed Primeau as he discusses creating Video Work Product for Forensic Investigations.

9: How to Recover Digital Media Evidence

Friday, November 7th, 2014

9: How to Recover Digital Media EvidenceI’d like to discuss evidence recovery, specifically digital media evidence recovery.  Having a forensic expert retrieve the evidence maintains the quality of the evidence and can help ensure that the original evidence stays intact on the original system so it can later be retrieved by other parties.  This is why it is extremely important that only a trained expert retrieve the evidence.  In this episode, I will cover proper procedures for evidence retrieval, proper handling of the evidence and what precautions one should take when retrieving digital media evidence from a recording system.

Steps for Proper Evidence Retrieval

1. Research before retrieving the evidence.  The forensic expert should learn everything they can about the recording system beforehand.  Connecting with the manufacturer, reading the manual and researching further online all benefit the expert.  This will make analyzing and operating the system onsite easier for the expert and optimize the retrieval process.

2. Obtain any necessary software, proprietary player or codec. If the system records proprietary or encoded files, the expert should obtain the player or codec beforehand.  If that is not possible, the expert should be prepared to install the necessary player or codec onsite from either the recording system or client.  More often than not, modern digital surveillance systems require a special codec or proprietary player and without this installed, the forensic expert will not be able to access the digital media evidence.

3. Record the evidence retrieval process. The forensic expert should record both audio and video of the evidence retrieval to include in the chain of custody and forensic report.  When I am recovering evidence from a digital recording system, I always have a VIEVU body camera on my person, as well as a digital audio recorder in my pocket.  Along with authenticating the evidence, this can serve as the expert’s notes later on in the investigation in case they need to refer to something that was discussed during the evidence retrieval.

4. Photograph and inspect the digital recording system. The forensic expert should include photographs of the unit in their report and take careful notes on anything they notice about the unit.  This could include damage, tampering or any other abnormalities they notice on the recorder.  Along with the video recording, it is usually beneficial for the expert to photograph anything they note during the process.

5. Follow the manual for the highest quality retrieval. The expert should have the manual with them when retrieving the evidence to make sure that any copy or export is in the highest quality format and does not affect the original recorded file.

7: Importance of the Chain of Custody for Digital Media Evidence

Monday, October 27th, 2014

7: Importance of the Chain of Custody for Digital Media EvidenceEstablishing chain of custody when authenticating digital media evidence for use in the courtroom is extremely important. The chain of custody must account for the seizure, storage, transfer and condition of the evidence.  The chain of custody is absolutely necessary for admissible evidence in court.

Importance to the expert

My forensic software allows me to look at the metadata or digital information of an audio or video recording, but does not always allow me to understand how a recording was created.  Just because the information is missing from the metadata does not mean that a recording has been compromised.  This is why the chain of custody information is important to a forensic examiner. It helps show where the file came from, who created it, and the type of equipment that was used.  That way, if I want to create an exemplar, I can get that equipment, create the exemplar and compare it to the evidence to confirm the file properties.

Importance to the court

When I testify in court with a piece of evidence, I am always prepared with the chain of custody.  As I mentioned earlier, without a complete chain of custody, it can become very easy for the opposing attorney or prosecutor to challenge or dismiss the evidence presented.  Having a complete chain of custody form, as well as any other accompanying forms and including any visual proof of retrieval, such as pictures or video, greatly helps prove the authenticity and admissibility of the evidence in the courtroom.

Recently, new ways of establishing a chain of custody have come about and are slowly becoming accepted in the legal community.  Online services are now available for digital evidence that record the chain of custody and who has received the evidence.  The evidence is stored in cloud space and eliminates the need for repeated transference of physical copies.  It maintains standardized security procedures and is also useful as a backup storage space for surveillance cameras.

Chain of custody is important to the court because if I find something wrong with the evidence during the authentication process, it allows me to go back and determine who was responsible for the evidence up until that point. 

Importance to the investigation

The chain of custody is important to the investigation process because it is the first step when authenticating digital audio and video evidence.  Identifying this chain of custody provides information about whether or not this evidence has been copied or cloned.  As technology advances and becomes more accessible, digital media evidence has become easier to edit, modify and alter.  The Scientific Working Group on Digital Evidence (SWGDE & IOCE) defines Original Digital Evidence as, “Physical items and the data objects associated with such items at the time of acquisition or seizure.”  It is not always possible to receive the evidence from its original source at the time of acquisition or seizure.  Very often, I receive digital media evidence from a client who may have received it from the police or another source.  When this occurs, I have to pay careful attention to the reports, depositions and other legal documents that accompany the evidence.  This paper trail must be part of an unbroken timeline that shows exactly where the evidence has been between its creation and my examination of it.  When I encounter any gaps in this timeline that can raise questions to the authenticity of the evidence, further investigation becomes necessary.

There are occasions when I am asked by the client to physically retrieve the evidence directly from the recorder that created it.  This process creates the chain of custody for my investigation.  When an expert creates the chain of custody, it removes all doubt as to the authenticity of the evidence.   This process has become more common throughout my investigations when the original evidence is available for my retrieval.  To further authenticate this process, I create audio and video recordings of the retrieval process, which becomes part of the chain of custody. In addition, when I am at the site and I retrieve the digital evidence, I have access to the administrator information about that evidence, such as an administrative log, date and file info, and who accessed the files.  The more information an expert can retrieve strengthens the authentic chain of custody that is created.

Primeau Forensics’ chain of custody process

  • Save original package materials
  • Take photos of physical evidence
  • Take screenshots of digital evidence content
  • Document date, time and any other information of receipt
  • Ingest a bit for bit clone of digital evidence content into our forensic computers
  • Perform a hash test analysis to further authenticate working clone

All of the above information outlined in our forensic procedure for creating a chain of custody is important and necessary to include when creating a forensic report.

When examining digital media evidence, especially digital audio and video recordings, you should never examine the original file.  Always make sure that when you process a piece of evidence, you work on the copy of that file so that the original remains untouched at all times.  That way, if you have to go back to compare your work product to the original, you’ll have that original file preserved.

It doesn’t matter what forensic science you are an expert in.  The chain of custody is always important.  Maintaining that chain of custody is crucial for the credibility of your work product and eventual testimony.

Video Forensic Expert – The Importance of Continuing Education

Friday, October 3rd, 2014

Video Forensic Expert - The Importance of Continuing EducationI have been practicing as a video forensic expert for 30 years. I have experienced and observed hundreds of hours, if not days, of security video. I have performed video forensic testing on analogue and digital security systems. I have even forensically examined cell and smart phone video, tablet video and VHS, Hi8 and 8mm, digital 8mm, digital and analogue beta and even ¾” video (which by the way plays from right to left unlike any other analogue video format). I write this introduction not to impress you, but rather express to you that I have been around the block a few times.

However, this week I experienced something new. I took a continuing education class in ‘Digital Video Processing Techniques’ taught by Dorothy Stout of Resolution Video Inc.

On the first day, we were asked to introduce ourselves and say what we expected to learn from the class. When it was my turn, I introduced myself and said ‘I don’t know what I don’t know. That is why I am here, to learn what I don’t know.’

Any forensic expert who thinks they know everything about their expertise is arrogant, especially in video forensics where technology is constantly changing. Dorothy took our class through three days of very interesting lectures about digital video processing techniques, software training and actual security video hands on assignments. Her demeanor and teaching style in the front of the class made these three days very invigorating. Learning was fun and easy thanks to Dorothy’s experience. She is sought out by government agencies, law enforcement and private practice video forensic experts like myself all over the country for video forensic training.

I learned about software programs, work flow, case management and most importantly, had my confidence boosted because I had already known quite a bit about the various video forensic processes that we covered and practiced.

Anyone with a passion for video forensics should consider taking one of Dorothy’s video forensic classes. I learned a lot and enjoyed the experience.

Forensic Experts Are Worth The Investment

Thursday, June 7th, 2012

Forensic Experts Are Worth The InvestmentWhen introducing a new litigator to audio and video forensics, I like to use the analogy of car repair. You can have your car repaired by a corner or back yard mechanic that charges forty dollars an hour. It might take that back yard mechanic ten hours to fix the problem. OR, you can take your car to the dealership which charges seventy five dollars an hour and have it repaired in two hours. The difference is in the experience and credibility. The dealership will also take the time and explain what needs to be repaired and provide options and an understanding of the repair process. The dealership’s experience with and knowledge of that make and model of the car saves them time making the repair and helps you the customer better understand the nature of the problem.

The same is true regarding a forensic expert. Forensic experts have experience with each forensic academic and can save litigators time and money when it comes to understanding forensic evidence and investigations.
Primeau Forensics is a vehicle for you to get answers to the questions you have about your multi-media evidence that is being used in litigation. As an audio and video forensic expert, I often find that courts, lawyers, and litigators get confused as to the purpose and the validity of their forensic evidence—which is where we help. Today there are dozens of CCTV digital video formats and audio recordings everywhere that contribute to evidence. That information needs to be simplified and better understood by courts and litigators.

Primeau Forensics is a growing forensic organization. It will soon include Internet forensics, security forensics, cell phone forensics, smart phone forensics, and other related multi-media forensic services. Audio and video is being recorded everywhere, not just CCTV (closed on circuit television systems) and police car dash cameras. Audio and video is used more today in litigation than ever before. Knowing some simple facts about your audio and video evidence from a forensic perspective is extremely important to you and the decision makers. Primeau Forensics is here to help. We welcome any questions, comments or feedback either by email– primeauforensics@gmail.com or by phone–(800) 647-4281.
