How Did We Get Here?

Orlando sentinel Paper with Twin Towers in background.When four US passenger airliners were highjacked and the Twin Towers came down on September 11, 2001, ubiquitous video surveillance was not yet part of the American landscape. In fact, the terrorists made their way through three of the nation’s busiest airports, Logan International in Boston, Washington-Dulles in Virginia, and Newark International in New Jersey, as the coordinated attack unfolded with just a single visual record of the movements of the hijackers. It was primarily due to a small eight-camera, analog video recording system at the Portland, Maine International Jetport, that we have any meaningful visual record of the movements of the terrorists that day. Earlier in the morning, two of the hijackers, Mohamed Atta and Abdul Aziz al Omari, made their way through a security checkpoint in the tiny commuter terminal on their way to Boston.

Using what was considered advanced video equipment at the time, Fredericks recovered the first clear images of the hijackers, helping investigators begin to put a face to the terrorists responsible for the deaths of 2,976 people.

In the following years, and primarily in the wake of the 9/11 attacks, video monitoring in the US and elsewhere became a priority for almost every public facility deemed to be part of a nation’s critical infrastructure. The exploding analog video surveillance market soon gave way to new, cheaper, and more complicated digital technologies. By 2011, just a decade after the attack on the US homeland, cameras could be found almost everywhere that the public had access, including buses, taxis, trains, grocery stores, schools, and even in our churches. Our surveillance society was complete.

Today, police from around the world are learning to effectively leverage the now prolific monitoring of our public lives in the pursuit of enhancing public safety and furthering criminal investigations. For most of the last eighteen years, Fredericks was the lead instructor for the Law Enforcement and Emergency Services Video Association (LEVA), an organization dedicated to training police experts in video analysis. LEVA maintains a Forensic Video Response Team, a group of certified police video analysts available to the US Federal Government in the event of another 9/11 style attack. The group could also be called on by any member police agency dealing with large volumes of video evidence. The first call-for-service for the team’s capabilities came from the Vancouver (Canada) Police Department in 2011.

Vancouver Riots Necessitate Large-Scale Video Examinations

A massive riot that took over the western Canadian city after the Vancouver Canuck’s lost the Stanley Cup hockey championship game to the Boston Bruins. The riots resulted in millions of dollars in damage, several serious injuries, including multiple stabbings and one fatality. The events were seen as a significant black-eye for one of Canada’s shining cities, the third-largest metropolitan area on the Pacific Coast of North Rioter from VancouverAmerica, and the site of the then-recent 2010 Winter Olympics. In an effort to identify and charge those responsible, the Vancouver Police put out a public call for all video evidence that could potentially be used to bring the rioters to justice. Investigators were unprepared for the response. Within a few weeks, over 5,000 hours of digital video evidence was turned over to police. The data had been recorded to almost 400 proprietary video recording systems. The VPD quickly discovered that each system had a unique requirement for access, including the need for specialized codecs, and other technologies in order to view the images. It was estimated that it would take investigators approximately two years to go through their video evidence. There had to be a better option.

Officer working on the Vancouver Riots video evidence.The Vancouver Police, a LEVA member-agency, turned to Fredericks with a request to activate the Forensic Video Response Team. At the time, Fredericks ran the National Digital Video Analysis Lab at the University of Indianapolis, the training headquarters for LEVA. For two weeks, Fredericks and his team of fifty police analysts from the US, Canada, and the UK, worked 24/7 in three shifts to process all 5,000 hours of video at the lab. ‘Each video started as a research project’ says Fredericks, who acted as the Technical Coordinator and Lead Analyst for the project. He explains that because the digital video evidence was in a proprietary format, analysts had to first determine the most reliable method of playback, even before the analysis could be conducted. At the end of the project, the team of experts had invested almost 6,000 man-hours collating, tracking, and databasing over 15,000 criminal acts, committed by almost 400 uniquely identifiable individuals. When the results of the video analysis were returned to Vancouver, detectives started the process of identification. At the conclusion of the investigation, more than 800 criminal charges were laid and eventually every suspect was convicted for various riot-related offenses.

What Did We Learn?

International Association of Chiefs of Police logo.The International Association of Chiefs of Police recognized the ground-breaking work by awarding LEVA the August Vollmer Award, the highest international recognition for Technical Advances in a Police Investigation. During their project debrief, Fredericks and his team acknowledged the complexities of examining proprietary digital video evidence and they recognized that there had to be a better way. The team determined that police investigators should not have to seek the assistance of experts or costly outside assistance, simply to view their video evidence. For the next few years, Fredericks and his team shared their experiences of the riot investigation to build and then perfect an inexpensive tool that could be used by any investigator. The result was iNPUT-ACE, a powerful, yet simple video workflow engine developed as a digital video viewer designed for every investigator. The easy drag, drop, and play interface bypasses the restrictions typically associated with accessing and examining complicated proprietary video files.

Unlike the initial investigation into the 9/11 attacks, when video evidence was rare, over 70% of criminal investigations today involve the recovery and examination of video. As a result, iNPUT-ACE is now the primary video tool used by hundreds of police agencies around the world.
