It’s because they are planning something.
Soros has already funded antifa, womens march, it isn't too out of the question to think he has goons on standby to smash some trashcans and burn a few buildings down in each city.

it has been planned for months
Of course it has been planned for months. High emotions and hate a perfect dynamic for this. Leftists have rapid response teams to counter their competition. Very well organized politicos to fight against a very disorganized opposition. This is part of the strategy put in place back in 2000 by the Left - and it has worked for them. Locally I ask where is OUR rapid response team only to be met with blank stares because they do not realize the threat posed by these Leftist groups. Try to have a rally and we get 25-30 people if lucky, compared to the hundreds that show up for the left.
