Cameras on police are mostly irrelevant. This has been proved repeatedly, at least as far back as Rodney King in 1992. We saw the video of the police beating Rodney King, but the police were nonetheless protected by the legal system. It's extremely rare for police to suffer consequences from their behavior.
Any minor transgression from most people will be punished severely. Even the worst transgression from powerful people will be forgiven. That's how our system works. Don't ever think that Orwellian surveillance will put everyone on a level playing field. As an ultra-powerful person, Larry Ellison is well aware of this.
In "a randomized controlled trial involving more than 400 police officers in Las Vegas, Nevada...officers equipped with body-worn cameras generated fewer complaints and use of force reports relative to officers without cameras. BWC officers also made more arrests and issued more citations than their non-BWC counterparts" [1].
More broadly, "there remains substantial uncertainty about whether BWCs can reduce officer use of force, but the variation in effects suggests there may be conditions in which BWC could be effective" [2]. ("Restricting officer discretion in turning on and off BWCs may reduce police use of force," and while "BWCs may reduce the number of citizen complaints against police officers...it is unclear why complaints decline.")
"Our meta‐analysis of 30 studies and 116 effects of police use of BWCs finds that this technology produces few clear or consistent impacts on police or citizen behaviors."
Overall, the effects are unclear. Drill in and there is statistical significance. It's not fair to say it's irrelevant, because we do have cases where it works. There are just more confounding variables than we've given attention to.
