No, to think the rioters (they aren't protesters ) will calm down.
They did in Ferguson when one of the rioters was shot dead by cops. The dead rioter's father was saying he didn't have a gun and was inciting more rioting. The next day the cops released a surveillance video showing the guy had a gun and that took the wind out of that part of the Ferguson protests.
If clear video evidence doesn't quell violent protests then all the people calling for dash and body cameras are the dumb ones.
