This is truly horrible, but I have to say that I'd rather have the government use proportionate force on bad players instead of using it on business owners to have them enforce some reactionary laws and in the process limiting the freedoms of the majority.

The state has the monopoly on enforcing rules and it should not fear forcing citizens to comply.

If the state for some reason cannot uphold order anymore then we are back at having survival of the fittest and might makes right on the streets.

I'm not defending trigger happy police men, but in this particular case police should have been watching this area and arrest and later charge everyone that hit somebody random in the head for attempted manslaughter, even if the victim didn't suffer any enduring damage.

I believe this would have sent a message.
