You mean they didn't make protests (mostly peaceful) over police brutality worse by employing more police brutality. That was actually... kind of sensible.
The point to avoid this was not when angry people were already on the street. The point to avoid this was before that happened by fixing the police departments.
Trump undid all the efforts that Obama started to reform the police, and openly encouraged police misconduct.
That's why you had riots. Not because what was done to George Floyd was more egregious than what was done to Tamir Rice or Laquan McDonald or Alton Sterling or Mike Brown or Sandra Bland... but because people had just had enough of it.
Actually, no. The National Guard is activated by the state. Which was done in November 2020.
Oregon Gov. Kate Brown activated the National Guard to assist local law enforcement in responding to protest violence in downtown Portland Wednesday night.

The problem with activating the Guard is that the Guard really isn't a substitute for the police.
They spend about one day a year on civil disturbance training. (Or at least that's what they did when I was in the IL Guard in the 80's). If you think the police are too timid, they have nothing on the Guard, who live in mortal terror of another Kent State.
When I was in, we had this one major who was giving the class on what we could and couldn't do. And the one thing he emphasized that stuck with me.
"Those are not the enemy out there. They are your fellow citizens, they are damned angry about something and they have every right to be!"
Um, yeah, because Trump gave us the worst recession in 80 years! Holy Shit, do you people even hear yourselves. I'm surprised you didn't try to claim all his Covid Deaths opened up job opportunities.
