NYPD violently storms peaceful concert of world-famous rappers

A lot of confusion there, not enough info for me to pass judgement at this point, but it does appear that police were very heavy-handed in dealing with the situation. I notice in one segment of the video below, that an officer assaults a man with a night-stick but did not arrest him. Without an arrest and charges, by what right did he assault the man with a weapon?

The key factor in this will be whether or not the venue managers allowed police inside, requested their assistance, or if police simply stormed the show of their own accord. And I will say this much, I have seen far more blatant abuses of police power than this. I think this could have turned out a LOT worse than it did.
