I'll throw an idea out there to keep zealous baseball fans in Chicago from running out onto the field and attacking people: stop selling beer at games.

Not like this will ever happen... And now for a little bit of violent baseball history in Chicago that I found on espn.com:

"July 13, 1979, Comiskey Park: Bill Veeck's infamous Disco Demolition Night, Fans who brought disco records were allowed into the stadium for 98 cents. The records were to go into a bonfire between games of a doubleheader with the Tigers. About 50,000 fans attended the game and more than 5,000 ended up on the field where a riot ensured. Veeck made futile pleas for the mob to leave. Umpire Dave Phillips called a forfeit, giving Detroit a sweep."

Heh.
