Once again for the slow and amazingly stupid. They were ordered to CLEAR the park. The right to assemble does not give you the right to camp in a city park in mass without the cities permission. It wasn't about jaywalking or litter. It was about physically removing people and their crap from a city park.
And there would have been no violence if the protestors had simply left. THEY chose to resist. They chose to counter attack to reclaim the park.
Again, what you just said gives States and municipalities the right to unconstitutionally ban firearms.
If you believe that States and cities cannot ban the bearing of firearms, then you must also logically agree with my point.
And, you used the phrase "counter attack", which implies self defense. People are allowed to act in self defense, even if it's against the police.
But there has been no proof presented that anyone attacked the police in the first place, now has there? Just Hearsay.
