Oh Charles, from your new found 'bub':
Police use of force is at the forefront of public awareness in many countries. Body-worn videos (BWVs) have been proposed as a new way of reducing police use of force, as well as assaults against officers. To date, only a handful of peer-reviewed randomised trials have looked at the effectiveness of BWVs, primarily focusing on use of force and complaints. We sought to replicate these studies,
adding assaults against police officers as an additional outcome. Using a prospective meta-analysis of multi-site, multi-national randomised controlled trials from 10 discrete tests with a total population of +2 million, and 2.2 million police officer-hours, we assess the effect of BWVs on the rates of (i) police use of force and (ii) assaults against officers. Averaged over 10 trials, BWVs had no effect on police use of force (d = 0.021; SE = 0.056; 95% CI: –0.089–0.130),
but led to an increased rate of assaults against officers wearing cameras (d = 0.176; SE = 0.058; 95% CI: 0.061–0.290).
As there is evidence that cameras may increase the risk of assaults against officers, more attention should be paid to how these devices are implemented. Likewise, since other public-facing organisations are considering equipping their staff with BWVs (e.g. firefighters, private security, traffic wardens), the findings on risks associated with BWVs are transferrable to those occupations as well.

We have previously reported results from a global multisite randomized controlled trial on the effect of BWCs on various outcomes, including use of force, complaints against the police, and assaults against officers (Ariel et al. 2016). Averaged over ten trials,
we reported that the use of police BWCs had no overall effect on use of force. However, our results varied, with force increasing in some trials and reducing in others. These conflicting results were puzzling and disturbing.
Why would officers, knowing that their actions were being filmed by their own equipment, choose to apply force more often when cameras were on in some instances? Similarly, why would suspects’ demeanor become more aggressive or noncompliant under these circumstances? This runs contrary to both common sense and a good deal of research across disciplines on the effect of deterrence on compliance behavior as well as the law (see Nagin 2013; in the framework of BWCs, see Ariel 2016).

So Charles, two enough?
Of course Charles, a concept to remember is the studies being brought forth are from those institutions, e.g., force science, criminalogy perspective, etc., which have a vested interest in representing the .gov Mr. McBeth was referring to.
