Obviously "urging peace" didn't work. In fact, they should have known it wouldn't.
Twenty plus people were killed during the riots and there were no less than seven shootings in the CHAZ with two of these succumbing to their wounds.
A 19 year old rapper was shot and killed on June 20th in the CHAZ and his mother filed a wrongful death suit against the city, claiming that if authorities had taken action to prevent or clear the occupation, her son would still be alive. A judge eventually tossed the suit but nevertheless, she was right.
It wasn't until a 16 year old was murdered and a 14 year old was shot (on the same day) that authorities finally decided to do something about it.
Given all this, can you tell me that Trump enjoying the events of Jan 6 made one whit of difference in the end?
