Police Complaints Drop 93 Percent After Deploying Body Cameras (techcrunch.com)
An anonymous reader writes:A study from Cambridge University documents an immense drop in complaints against police officers when their departments began using body cameras. But even more surprising is that the data suggests everyone is on their best behavior whether the cameras are present or not. The data was collected in seven police departments, and represents over 1.4 million hours logged by 1,847 officers in 2014 and 2015; the researchers published their data last week in the journal Criminal Justice and Behavior. Officers were randomly assigned to wear or not wear cameras week by week (about half would be wearing them any given week), and had to keep them on during all encounters. The authors used complaints against police as a metric because they're easy to measure, an established practice in most police forces and give a good ballpark of the frequency of problematic behavior. In the year before the study, 1,539 complaints in total were filed against officers; at the end of the body camera experiment, the year had only yielded 113 complaints.
The most important thing is the end of the article.
"Specifics on how exactly this is happening are unclear. Is the officer less confrontational to begin with, avoiding escalation? Or are suspects and complainants more wary of their conduct? Is it some combination of the two, or are even more factors involved? To determine these things would be a far more complex and subtle piece of research, but the study does suggest that officer behavior is probably the most affected, and that other effects flow from that."
Someone already said it is the people acting better or making less complaints because they think they may be on camera. I am certain someone is writing, it means the police are behaving themselves.
I would guess (not scientific) that most of the drop in complaints are because people realize they might be caught on camera and acting better or not lieing to try and get a lawsuit. I am certain there are some police that are acting better as there are bad apples, but I would guess the drop is probably 10%/90% with the 90% being the people changing behavior as opposed to the police office.
