Here is an interesting quick read about the Australian experience with body worn cameras (BWC). I selected it from the search results since many of the US-centric results are sourced from DoJ or similar which may be seen as less than objective.

My takeaway is that like anything, generalizations miss a lot. BWC have lead to more efficient triage of complaints against police officers that even if sustained reduce the substantial amount of uncertainty. It is an open question to what degree BWC neutrally observe police behavior which is better than anecdotes or if the presence of the observer alters police behavior to meet standards.

Interesting. I for one wish cameras rolled constantly in cars and on body. I would think it should improve outcomes for everyone abiding by the law. I just don’t know in the US how much local police appreciate wearing them. I go back to the 2010s when they started rolling out and it was a pretty large sticking point with most of the unions. Hence I would be surprised cops have changed that much.
