Active NYPD and STH here. Just want to chime in.
It's the Yankees' house, they run the show. Criminal acts aside, if they want someone out, you're out. You refuse, it's trespass and the cuffs come out. I know everyone loves to blame cops, but chances are, ejections have merit to it. Even if they don't, take it up with the landlords.
Most people don't see the cops' side when it comes to policing post-event madness. I do. It's, well, madness. 99% of the fans are no trouble, the 1% are a pain in the @$$ and force the hand. Videos often show the final 10% of an encounter and the narrative is then, "cops ruin fun". Keep in mind the oft-ignored and less-exiciting public safety aspect. Minor, small scale "bad behavior" tends to compound quickly and uncontrollable craziness ensues. You'd be surprised how similar this is to wildfire. That's one of the reasons cops are there in the first place.
I can't speak for in-stadium issues, but as for post-event police activities, this is no different than a Yankee game. A lot of "little" violations are overlooked, but knuckleheads who ignore calls to get out of the street and things of that nature are sure to end up arrested or summonsed. Also, the precinct which covers the stadium gets bombarded with complaints at council meetings about post-event fan behavior (baseball, soccer, concerts, you name it). As mentioned above, these have to be addressed by commanders.
I just wanted to explain the other side. There isn't some conspiracy to shut down the club or harass fans, or some nefarious "us vs. them" ploy that requires moving the team to Westchester. I know tons of cops who are STH, and the club sticker has already been plastered on several lockers and department facilities alongside those of the Jets, Yanks, and Rangers. Anyhow, I digress.
TL;DR: Don't act like an ass, stay out of the street, use common sense. Odds are, you'll be fine.
