It won't be long until someone runs over a bunch of those punks and gets arrested for it. At that time, I hope whoever it is files multiple lawsuits against the Mayor, the City, the Chief of Police and the City Council.
The grounds should include but not be limited to, dereliction of duty, aiding and abetting Domestic terrorism, Failure to keep the peace, Endangerment, Willful Negligence resulting in Bodily Harm, Multiple Civil Rights violations and probably at least a half a dozen more reasons.
I'm surprised The Feds haven't already stepped in.
