If he was trying to protect people, he wouldn't be holding the rally in the first place. I know this is hard for you to follow but its circular reasoning. If he knows there's a chance of violence (however small it is), you don't hold the rally. You don't hold the rally when there is a pandemic still sweeping across the nation.
And if you are going to spit in the face of all those things, you don't group peaceful protestors with agitators, looters and lowlifes. They aren't the same thing.
