This case has done nothing more that affirm that police have the right to assault you even if you are not a physical threat to anybody.
What’s next? Getting tased because you failed to mow your lawn? Oh wait...
Failing to mow your lawn is not in and of itself an offense requiring the use of force. A person who becomes belligerent and aggressive after being asked by law enforcement to maintain his property is.
He resisted. After he said that he would leave peacefully, he tried to break free and charge towards the stage.
Comparing his actions to mowing your lawn is just disingenuous of you.
