The ones in DC at the time weren't rioters. They were peaceful protesters.
You can literally see that in so many videos. It's not like these people were all attempting to break into the WH. Trump had a plan where he wanted to go to the church and take a picture -- but he wouldn't be able to do so because there were protestors in the surrounding areas (where they're allowed to be protesting) Everyone in this country has a right to peacefully protest.
In some areas are people rioting? Yes.
Are the majority of people rioting? No.
Did the authorize the use of force against peaceful protesters to take his picture? Yes.
Like.....
OH WELL IN THAT CASE! I guess we can just ignore all of this and pretend it is all perfectly safe and that these "peaceful protestors" weren't throwing projectiles and setting shit on fire among other things because dipshits like you unilaterally declare them "peaceful".
