I was just awaken by a huge fight in the hallway one floor below me (5:00 am).  Bunch of drunks just fighting with each other.  They carried on for about a half hour.  One guy kept telling someone else "let's just go, let's go to the hospital".   I could see thru the reflection on the windows ( there is a sort of atrium that connects every other floor).  Young, men and women -woke everyone up.  The neighbor across the hallway also walk up and came out (I never saw another soul on my floor in the 7 month's I've lived here).
All someone had to do was call the police and they'll be lots of trouble.  I actually yelled down to them "guys, calm down and go away before the police come".  Of course they did not listen and are still loitering.   
Dumb really.
