A conducted energy weapon was used by police, after which an ambulance was called when the man appeared in medical distress.

More imporantly, to make sure your evidence leads to the truth and remains valid in the court of law, let’s examine some important concepts involved in video recovery from common digital devices.

However, more video enhancement possibilities also increase the misrepresentation possibilities, and one should be even more careful to preserve the integrity of the video while using advanced video enhancement techniques.

When it comes to conducted energy weapons, Dunn said Greater Sudbury Police follow Ontario Use of Force Standards, which intends for them to be used when:

Do not discard or change the original media even after extracting your required videos. When you export a video from a device, it is transcoded and loses some of the detail as well as metadata associated with the videos. If possible, it is always preferable to operate the original device as read-only and preserve the original data.

The Council of Canadian Academies & the Canadian Academy of Health Sciences’ 2013 report notes that conducted energy weapons deliver short-duration electrical discharges, which are highly effective in stimulating nerves, causing incapacitation and pain, but are much less effective in stimulating the heart muscle, which means they’re less likely to cause fatal disruptions to the heart’s rhythm and pumping ability.

An inquest jury later ruled Couvrette’s death was an accident. During the inquest, the conducted energy weapon was ruled out as a contributing factor in his death.

She also declined to share whether the patrol officer who used the conducted energy weapon on the 46-year-old man on Tuesday is still on active duty, as Greater Sudbury Police “are prohibited from providing further information related to the incident as it is under investigation by the SIU (Special Investigations Unit).”

“We are required by legislation to publicly provide an annual use of force report through our Police Services Board,” she wrote.

In 2022, conducted energy weapons were taken out but not used 62 times, and they were taken out and not used 50 times in 2021.

Consequently, video forensics, as such an indispensable skill, enables you to consider the strengths and limitations of the video evidence and draw the right conclusion

“Sudden in-custody death resulting from a use-of-force event typically involves a complicated scenario that includes multiple factors, all of which can potentially contribute to a sudden unexpected death,” according to the report.

A picture is worth a thousand words and a video is a silent witness that speaks for itself. Isn’t it? No doubt a video can be powerful evidence, but there are many factors that might affect the availability, integrity, and interpretation of their reliability, making it less effective or even misleading.

In such cases, it is advisable to reach a video forensics analyst or a digital forensics solutions provider like SalvationDATA.

The weapon was deployed for 11 seconds, but reportedly did not successfully attach to Couvrette’s body to complete the electrical circuit.

If you come across a device that uses propriety or obscure file system and codec, you need to do a lot of research to lay your hands on the video. In case you are not a forensic video analyst and for the best practice, do not experiment with the original evidence lest you render it unusable.

The 29-use count in 2022 is a jump from the previous year, when Greater Sudbury police used conducted energy weapons 17 times.

Playing a video on one device and capturing video through the camera of another device is a very poor way to collect evidence. It seriously compromises all four important factors of video integrity: shape, size, color, and timing.

Viewing the video carefully is often the first step in video analysis. Start noticing the areas of interest while viewing the video so that these areas can be investigated further.

Video forensics tools have been developed to extract and read most proprietary file systems and video codecs. However, with a very large number of file systems and codecs, even a video forensic tool might not be able to extract the video footage.

Video forensics often starts with the recovery of the video footage. Meanwhile, not only do today’s video capture devices come in a variety of shapes and sizes, but use different software, file systems, and codecs.

Keep in mind, It is your skill as a digital forensic investigator and your understanding of forensic video analysis that enables you to observe all factors of interest and draw correct conclusions.

Video evidence is abundant, from CCTV to mobile and body cameras, and it is only expected to increase. But to get the most out of it, every Digital Forensic Investigators need to know the basics of video forensics.

Aims to resolve the problems of deleted /corrupted/fragmented database files, false file systems, and restriction of application system accessibility.

From Rodney King to George Floyd, video evidence has played a key role in forming a public opinion as well as reaching a verdict. One must remember, the video itself is neither weak nor strong evidence but an opportunity to notice and interpret, just like any other type of evidence. It is the abundance and objectivity of the video that makes it such an important type of evidence.

Forensic video analysis includes a detailed investigation documenting the course, reason, culprits, and weapons involved in the incident, though, It can be a simple one where you only want to identify the victims and their position or know the position of witnesses to validate their observation.

Though you do not need to be a video forensics analyst or expert to utilize video files as evidence, you do need to know the answers to some basic questions.

“The report compiled by our Training Section provides a thorough and in-depth analysis of the information. This occurs in February or March of each year and will once again be provided at that time.”

“To date at least 33 deaths have been proximal to CEW use in Canada, but were not necessarily results of CEW deployment,” a 2013 report by the Council of Canadian Academies & the Canadian Academy of Health Sciences reads.

Perhaps best known by the brand name Taser, or its “stun gun” nickname, conducted energy weapons (CEW) are either fired (a pair of metal darts are shot into the person) or used in a drive stun (the device is pressed directly on a person).

“This makes it difficult to isolate the contribution of any single factor. Although the electrical characteristics of CEWs can potentially contribute to sudden in-custody death, given the limited evidence, CEW exposure cannot be confirmed or excluded as the primary cause of a fatality in most real-world settings.”

These weapons are the same as the one used by police in Chelmsford on Tuesday before a 46-year-old man died in police custody.

A Jan. 23, 2021, incident in Sault Ste. Marie was also included in the trackinginjustica.ca list. In this case, police used a conducted energy weapon on a 30-year-old man, who proceeded to pull a knife out of his pocket and slit his own throat, according to the SIU investigation’s findings. The pathologist at autopsy concluded his cause of death was the stab wound to his neck.

To unveil the above questions in colloquial for you to easily understand, the following 3 broad categories: Forensic video recovery, forensic video enhancement, and forensic video analysis for comprehending video forensics would be the best concerns to start with.

Video forensics is the scientific examination and evaluation of video footage in legal matters. Analyzing a video was a relatively straightforward task in the days of analog video, but the spread of digital video changed everything.

Other than analyzing the complex and fuzzy video files only by yourself, working with a professional Video Forensic tool, like VIP 2.0 could save most of your time and cost, further, bring out more potential clues you unable attention to due to the video evidence files themselves.

Sudbury.com reached out to the Office of the Independent Police Review Director for the latest statistics regarding deaths related to conducted energy weapons, but they said they do not collect this data.

Though you don’t need to know all about them, you do need to know the concept behind to make sure you’ll get the most available clues out of your video evidence.

For the better practice of forensic video analysis, there is a myriad of factors to consider while doing a forensic analysis of video evidence.

They record 758 instances in Canada of police-involved deaths wherein force was used since 2000, of which 40 involved a conducted energy weapon as the highest level of force. Ontario led the pack among Canadian provinces and territories at 14 deaths, not including Tuesday’s incident in Chelmsford.

The crowd-sourced website, trackinginjustice.ca, keeps track of police-involved deaths and deaths in custody across Canada, noting, “there is no publicly available, verified, sustained, and comprehensive source for this information.”

Video enhancement is the process of enhancing the video and making it more suitable for a specific application. For example, zooming in a particular area might offer insights that are not apparent in the original size. Enhancing video evidence for digital forensic purposes, however, is more complex than just zooming.

Which is known to us all is that a video can be misrepresented based on shape, size, color, and timing, and when these crucial factors are misrepresented, they can lead to the wrong conclusion.In other words, you might need to do advanced operations like video comparisons, height identification, and speed analysis for complex video analysis and even further advanced forensic video analysis.

When enhancing a video, you want to bring out the details of interest already present in the video. You need to be careful of the enhancements that might add something that was not originally there, compromise the integrity of the evidence, and might lead to the wrong conclusion.

A Special Investigations Unit spokesperson told Sudbury.com they didn’t have this data, either, deferring to the Office of the Chief Coroner, who deferred back around to the Special Investigations Unit, but pledged to keep looking into it. Sudbury.com will update this story in the event the Office of the Chief Coroner sends additional context.

Although the SIU has indicated that the man in Chelmsford on Jan. 2 suffered cardiac arrest after police used a conducted energy weapon on him, his exact cause of death has not yet been determined. The SIU investigation is ongoing.
