You might try googling “fleeing felon rule”.
When you assault a police officer and grab his weapon, you have committed a felony.
You Police State boosters STILL are completely ignoring the fact that Walter Scott bravely ran away.
Slager then had to chase after him, and catch him. Scott wasn't assaulting anybody.
What you'd have posters like me & Digital Handyman believe is that once Slager donned his magic cape-suit with its powerful shiny amulets, that chasing after a person, catching them, and assaulting them is no longer an assault because of the special gew-gaws.
IN FACT, if The Magic Person was to grab the assaultee, or punch the assaultee, and the assaultee responded in kind, then SUDDENLY, the assaultee becomes a Felon Assaulter, and Stern Measures can be taken to suppress the former assaultee, including Tasing & back-shooting.
Neat trick, that.
Slager should have kept his dumb behind planted in the squad car, trying to find a satellite view of Walter Scott's address on Google Maps, instead of trying to invoke his Magic Trick in front of a video camera.
There'd be more of a chance of me agreeing with your position if Walter Scott hadn't been CONSISTENTLY running away. The whole time.
