Well, it must officially be spring.  The good students of MSU had another party which ended in a riot as usual.  There were about 3000-4000 kids at the party and the East Lansing PD ended up using tear gas.

A couple of police cars were smashed and officers reported being hit numerous time by various objects which were thrown.   But, no couches were set on fire.  (This is due to an ordinance banning couches from porches.)

I guess the kids enjoy tear gas.
