The LEFT/DEMOCRATS are dangerous - here’s the play-by-play of the Denver Shooting: https://www.denverpost.com/2020/10/12/denver-protest-shooting-photos-full-sequence/
I think that breakdown is actually helpful to the shooter. It shows the reporter (I guess... the guy in the BLM shirt anyway) getting in the face of the victim and a heated argument. The killer then steps in between and puts his hand (no gun drawn yet) on the victims chest to separate the two (sort of thing I'd expect a bodyguard to do) and gets a slap in the face in return. That's when he goes for the gun, after he was hit by the guy he ultimately shot.
It doesn't look like a politically motivated hit from those frames. Excessive force? Yup. Murder? He'll make a case that he feared for his life after the guy hit him and pulled mace. What a jury does with that is anyone's guess.
It is ironic that a guy who apparently supports BLM's war against cops defending themselves would end up shooting a guy to death and claiming self defense.
