I was surprised/bummed to learn that a large police body camera RCT in DC[1] found no significant effects on use of force, complaints, etc—& similar results in London [2]. But a Rio de Janeiro study[3] found huge impact. I wonder why so different… (links to papers in thread)

A broader review of the literature [4] suggests that the data's pretty muddled, possibly because of discretion in when the cameras are turned on. Naively, that makes me wonder whether there's some reasonable solution for keeping them on all the time "when in the field".

Or maybe cameras just represent an unhelpful wish for a simple technological silver bullet to a complex problem. 🤔

One plausible suggestion from is that while body cameras may not move general use-of-force metrics, they can mitigate very serious infractions (e.g. body cams have caught officers planting incriminating evidence). cato.org/blog/body-came

i’ve been reading and evidence shows that where police unions exist, more cops violently attack & kill minorities. and it’s causal, so as unions were created, violence went up.
i don’t think other countries have the same kind of systems

Jurisdictions where there are police unions result in 40% more violent misconduct. static1.squarespace.com/static/55ad38b
