Replying to So my friend is fucked

So last night my friend threw a kegger at his house while his parents are out of town. Earlier in the week, he sent w facebook message about it and it got blown up hella, so he told everybody he canceled it. But he only told some of the people that it wasn't canceled. So last night it starts off pretty good, but then around 9 it starts getting hella packed with kids a lot of people dont even know and the whole party starts going south hella quickly. At about 9:30 a fight broke out and it let to people getting bottle smashed, multiple windows broken and people getting hurt. At that point I got the fuck out of there. Within about 10 minutes of me leaving, multiple cop cars showed up. Hella people got cuffed, a kid got a shotty held to his head, and some people got taken to the hospital for their injuries. So my friend is about to get fucked when his parents get home and find out, because he can't hide all the damage.
