The second step is designing and training computer vision and speech analysis models that are able to learn from the data and automatically recognize target activities in new videos. The interface allows for rapid spatio-temporal coding of key activities in the video, partially automating the process to minimize required human intervention. Methods: The first step is developing and deploying efficient audio and video annotation interfaces. Our automated system will streamline this process and offer a new data source to study classic questions relating to police oversight, the dynamics of violent escalation, and racial bias in policing.ĭata: Body-worn camera footage from the Chicago Police Department (made publicly available by the Chicago Office of Police Accountability) body-worn camera footage from two municipal police agencies acquired through data sharing agreements body-worn camera footage from additional agencies once an alpha version of the automated system is operational. Body-worn camera footage represents a valuable source of data that has gone largely unused due to the time and cost needed to manually review thousands of hours of footage. Decades of policing research have relied on self-reported accounts of police-civilian interactions written by police officers. State police have not released body-camera video of any those cases, but AP obtained footage from the May 2020 arrest of Antonio Harris, who sped away from a traffic stop and led troopers through rural Richland Parish at speeds topping 150 mph before his car was finally stopped with a spike strip.Research Question: What happens during police-civilian interactions? This ongoing work seeks to develop computational methods to automatically generate summaries of police-civilian interactions captured by body-worn cameras. And like Greene, all the suspects were driving alone, were unarmed and didn’t appear to resist after troopers closed in. While none of the other beatings that prompted the broader review of Troop F resulted in deaths, all led to felony charges against some of the troopers involved. Master Trooper Chris Hollingsworth, who was recorded on his body camera bragging that he “beat the ever-living f-” out of Greene, was told he would be fired last year just hours before he died in single-vehicle car crash. Trooper Kory York, who was seen dragging Greene, was suspended without pay for 50 hours.
No troopers have been charged in Greene’s arrest. “They’ve got to identify these people and remove them from the organization.”Īn autopsy report obtained by AP lists Greene’s cause of death as “cocaine induced agitated delirium complicated by motor vehicle collision, physical struggle, inflicted head injury and restraint.”
That’s why you’re seeing this audit, which is a substantial undertaking by any agency,” said Rafael Goyeneche, a former prosecutor who is president of the Metropolitan Crime Commission, a New Orleans-based watchdog group.
“You’d be naïve to think it’s limited to two or three instances. The review is focused on Louisiana State Police Troop F, a 66-officer unit that patrols a sprawling territory in the northeastern part of the state and has become notorious in recent years for alleged acts of brutality that have resulted in felony charges against some of its troopers. The panel began working a few weeks ago to review thousands of body-camera videos over the past two years involving as many as a dozen white troopers, at least four of whom were involved in Greene’s arrest. “I don’t want to see this happen to nobody - not to my worst enemy.” This image from video from Louisiana state police state trooper Dakota DeMoss' body-worn camera, shows troopers holding up Ronald Greene before paramedics arrived on May 10, 2019, outside of Monroe, La. “Every time I told him to stop he’d hit me again,” said Aaron Bowman, whose flashlight pummeling left him with three broken ribs, a broken jaw, a broken wrist and a gash to his head that required six staples to close.
