I am squarely on Scott's side on this one. Did you watch the dashcam? Where to begin with this pig.
Everlast song interfering with audio a bit. Unprofessional.
Cop must state reason for stop before asking for ID, insurance, registration. Can't just check ID with no "crime" being present and the checked ID being suspect of said "crime". Slager clearly power tripping already from the start, walks up to the window, "got some ID?" That's a no no that we all should resist. No way, you want my ID for what exactly? Matter of fact ID yourself first; name, rank and badge number then state why you feel entitled to my ID.
Scott was cooperative, then he bolts. Was he guilty of something? Who gives a fuck atm, you have his ID so put out an APB or run him down the right way or whatever, call for backup.
Cops gun is not their backup its their life saver. Slager's life was not threatened in the least and a taser was not even justified.
You obviously don't know me very well, I like police that do their job, but I hate power tripping pigs.
