I like how you ignore the part that the police chief is telling us that he doesn't care about the investigation result.
As I said, it's possible that the investigation could turn out that an evil wizard cast a magic spell to conjure an illusion of the events that we saw and actually the 3+ video angles were fake, but discounting arcane intervention - really?
He wasn't really fighting cops, the extent of his action was walking between a cop and another protester a cop was shoving over. He didn't really have any time to do anything else before getting pepper sprayed several times and falling over on the slippy ice.
Again, Minnesota does not have Duty to Inform unless asked. Surely it's the whole point of a concealed carry permit that you are permitted to carry a weapon in a concealed way. Any police operating in Minnesota ought to know that!
they can reasonably assume
It is not a reasonable assumption that anyone with a conceal carry will have multiple teeny tiny handguns hidden all over their body, and that even if you've disarmed them of one handgun, then any following wiggle (likely brought about by the slippery ice, pepper spray, and five different dudes jostling him about) should be intepreted as deadly intent that you must react to by magdumping into their back.
Lots of americans conceal-carry; it's really not THAT suspicious of a behaviour! You can't shoot them all, they're like 8% of the country apparently!
any sudden movement toward your own body
He wasn't really making sudden movements, mostly just slipping on the ice with his arms on the ground and being jostled by the ~5 different men all simultaneously either grabbing him or hitting him.
He made *one* sudden movement, at the end, after he gets shot in the back and all the people grabbing him get startled and jump back in surprise and let him go.
are you kidding yourself if you think anybody buys that you don't want chaos and bloodshed.
The only chaos and bloodshed I'm seeing here is ICE picking fights with protesters at random with the most transparent of reasons, beating the shit out of them in a messy and chaotic way, and then magdumping into them while they're prone on the ground held down by multiple people! Literally shedding blood! That's chaos and bloodshed!
