I'd totes be down for 24/7/365 body cams on all cops. Not sure what is involved with ACTUALLY making that a reality, though.
That being said, Jesus, people need to stop acting stupidly in front of cops. I was pulled over once because my vehicle (at the time) matched a description of an armed robbery in North Seattle minutes earlier and I obeyed every word the cop said. I was definitely nervous, because I've been pulled over for speeding and a dead tail light a couple times, and this was NOT that.
I just don't have sympathy for anybody who does anything BUT completely and utterly comply with a cop's wishes when it comes to being pulled over, or initially questioned about something, etc.
By all means, lawyer up and don't answer awkward questions or whatever, but sudden movements and the like if a cop says freeze? I don't get it. It's just stupid.
Maybe the NFL can "loan" the money to police municipalities for body cameras, lol.
