New Report: Use of Body-Worn Cameras sees Complaints Against Police 'Virtually' Vanish
Body-worn cameras are fast becoming standard kit for frontline law enforcers, trumpeted by senior officers and even the US President as a technological ‘fix’ for what some see as a crisis of police legitimacy.
Now, new results from one of the largest randomised-controlled experiments in the history of criminal justice research, led by the University of Cambridge’s Institute of Criminology, show that the use by officers of body-worn cameras is associated with a startling 93% reduction in citizen complaints against police.
Researchers say this may be down to wearable cameras modifying behaviour through an ‘observer effect’: the awareness that encounters are recorded improves both suspect demeanour and police procedural compliance. Essentially, the “digital witness” of the camera encourages cooler heads to prevail.
An experiment took place across seven sites during 2014 and early 2015, including police from areas such as the UK Midlands and the Californian coast, and encompassing 1,429,868 officer hours across 4,264 shifts in jurisdictions that cover a total population of two million citizens. The findings are published today in the journal Criminal Justice and Behaviour.
The researchers write that, if levels of complaints offer at least some guide to standards of police conduct – and misconduct – these findings suggest that use of body-worn cameras are a “profound sea change in modern policing”.
“Cooling down potentially volatile police-public interactions to the point where official grievances against the police have virtually vanished may well lead to the conclusion that the use of body-worn cameras represents a turning point in policing,” said Cambridge criminologist and lead author Dr Barak Ariel.
“There can be no doubt that body-worn cameras increase the transparency of frontline policing. Anything that has been recorded can be subsequently reviewed, scrutinised and submitted as evidence.”
