Who is this security you speak of at after hours games? Seriously.... I'm pretty sure the school cops are only around during school hours and not at every event, unless something changed? Also as far as I know not every high school even has one of those security officers, mine didn't when I was there.

That's kind of the problem, it comes down to whatever small number of school officials (usually under 5) who are actually at the game and making the decision to call the police on a parent is a hard line to cross, especially when the asshat will always scream freedom of speech if the police come after them.

As much as I consider it abuse and harassment if they aren't actively assaulting someone the police don't usually want to get involved and then you have a teacher trying to forcibly remove a parent. We don't give them the resources to do things like that in small towns....
