To school insurance companies, pb is too dangerous to sanction entirely. Look around your class...see the guy in the back, index finger second-knuckle deep in his nostril? Yeah, he'd want to play. That kid over there, that says "jello" when asked "what's four plus four?" yeah, he'd want to play, too. While football and other such "mainstream" high school sports have built in controls to keep the idiot factor in check, paintball has no such monitoring.
Football and other "mainstream" sports bring $$ into the school. As much as I hate to admit it, I don't see paintball bringing in that kinda cash.
