went ahead and did a bit of googling:
In 2012, the police department in Rialto, California, in partnership with the University of Cambridge-Institute of Criminology (UK), examined whether body-worn cameras would have any impact on the number of complaints against officers or on officers’ use of force.
Over the course of one year, the department randomly assigned body-worn cameras to various frontline officers across 988 shifts. The study found that there was a 60 percent reduction in officer use of force incidents following camera deployment, and during the experiment, the shifts without cameras experienced twice as many use of force incidents as shifts with cameras.
The study also found that there was an 88 percent reduction in the number of citizen complaints between the year prior to camera implementation and the year following deployment. Chief of Police William Farrar of Rialto, who oversaw the study, said, “Whether the reduced number of complaints was because of the officers behaving better or the citizens behaving better—well, it was probably a little bit of both.”

crockett, body cameras go a long way toward resolving the issue.
