The key word is “Drunken”. The leftys will be stone cold sober{ At least from booze anyways} while the Fans will, well, drunk.
It would be a interesting matchup.The cops would just stand aside and arrest the winners and what remains of the losers.Either way, a rare “win-win” For Pittsburgh. As long as the police dont have the Pirates help with the mop up.
I think that if I were among Pittsburg's finest, I'd simply arrest the lefties after the skirmish, regardless of who won. It would be interesting seeing Cleveland and Pittsburgh fans fighting on the same side, though. If that is even possible.
