Northern Illinois University (NIU) just had a stabbing occur over someone being denied entrance to an fraternity party. The alleged perp is being charged with attempted murder, and NIU is suspending parties.

While an incident this serious doesn't happen every weekend, there do seem to be a lot of fights, scuffles, attacks, etc. associated with the problem of who does / does not get into (or asked to leave) a fraternity party. The large "open" (or nearly open) party concept may need to be rethought on quite a few campuses.
