With all of the law enforcement agencies that have said that they refuse to work the convention, my opinion is that they are trying to avoid a repeat of Chicago 68.
I wonder if the leftists will attempt to burn the city down,anyway.
Just think of all the Antifas, BLMers, man buns and other trash who had planned to raise hell at the conventions and now are out of luck.
Like you say, they will be very upset to lose such an opportunity and will probably riot anyway. But it will be a peaceful riot.
