Right, Federal court protected that right. Bet Black Lives Matter,  Black Gorillas( rebranded Black Panthers),  and Chaos were there. Confrontation was a planned test by all fronts to see what the government is going to do about it. Looks like both sides  came equipped, people with attitude, flags (to rally around), uniforms, and armour (shields, helmets, sticks, improvised flame thrower) along with a new police attitude, tolerance, which is interpreted as weakness by some. Actually more interesting than pre season NFL.
