I guess I don’t think that would happen. Singled out in the street, they are easy targets for abuse. An armed group, not so much. I don’t think the cops want to risk it either. They aren’t soldiers. Even the most racist and thuggish cops do what they do when they know they can’t be touched. When it is one sided. A large enough group means some cops would die too. Is it worth esculating the violence? Not for most cops, they want to go home to their wives and kids. And I know it is a bad example because it is a mixed group, but when in a group, minorites have open carried in protest with no harrassment. Alone they are targets and treated like threats.
Correct me if I am wrong, but didn’t they work to change the laws for the Black Panthers in the 60s, not shoot them in groups? And if they couldn’t get away with it back then before the civil rights laws changes, I don’t see it happening now.
That said, I could also see someone on either side start shooting and bad things happen. And I imagine either peaceful or violent, it woudl be spun negatively in the media. This is why my first post didn’t encourge the method to be increased in use. This is probably why we don’t see it used among minorities in protests often, though I have read people suggesting they do so.
