Axon has been the leader in PD dash cams and body cams for at least 15 years. PD in my old town had them back then. Good cops like them, they protect the cop from idiot citizens. We had one case where a citizen lied like hades about a cop interaction. In court. Solicitor pulled out the (new-ish at the time) body cams video that proved the cop in the right, the citizen a complete horse’s behind. Judge was not amused at the citizen lying to him, threw the book at the guy.
I once met the inventor of the police dash cam. He said the same thing
