There's absolutely no excuse for this rioting bullshit. Where people have acted within their rights, they've been allowed to do so. When they've rioted, they've been shut down. When they've been coddled completely and no attempt to maintain order has been made, they've burned shit down, destroyed businesses, and murdered people.
Nowhere that the police have made a reasonable effort to control the situation has it gotten out of control.
"Black people used to live here." So the fuck what? Do you see Jews going up to Harlem screaming that Jews used to live there?
