The NIJ itself expresses caution.
There are - just go look - numerous issues with the actual real-life performance of body cams.
I'm not saying they are necessarily useless. I am saying they shouldn't be viewed as a panacea and they shouldn't be advocated for uncritically.
Either by the people who think they would stop police violence or the people who think they would exonerate cops.
Simplistic tech solutions to systemic problems aren't going to happen and it serves no good purpose to be blindly uncritical of them.
The NIJ report of 2022 lists reports that are purely geared to criminal charges. For instance 4 out of 10 responded with not effective , one with the following comments:
Officers wearing cameras had statistically significant reductions in complaints filed against them and made more stop reports. Camera use resulted in a statistically significantly reduced likelihood of lawful stops and frisks but fewer subjects searched.
There are no 100% solutions but you can't toss an important tool away because it doesn't solve everything. I sympathize with cops and understand the bond of covering each others back against the bad guys. However there are bad apples and misplaced loyalty can usurp the rules they are suppose to enforce. Close to home - remember the kid alone on a streetcar who was basically murdered by an overzealous cop ? He was only caught because of video footage. There are hundreds of other cases where cops have both been exonerated and convicted based on body cams.
I cannot fathom an excuse not to have the police wear body cams or any other public enforcement officers. (Okay, undercover cops should get a pass
)
To end with an article that uses your terminology:
In San Antonio, body-camera video appeared to play a key role in the murder case filed last week against three police officers in the fatal shooting of 46-year-old Melissa Perez. ...
.. While body cameras aren’t a
panacea, in many departments they’re also being used to train officers on good policing. New York’s Metropolitan Transportation Authority Police keep a library of recorded interactions where officers defused situations well, a tool that’s invaluable for its immediacy and specificity.
Yeah because if we can't see it, it ain't happening.
Good point ! How about body cams on the homeless ? Put the edited cuts on a reality TV series and you can feed them with the profits. It might be the first reality TV I'm willing to watch.
