Found this on the Illinois law at
http://www.naso.org/PressReleases/st130.htm:
"The Illinois Senate and House approved two bills this afternoon that protect sports officials at all levels of competition from threats and assaults.
Both House Bills 4023 and 4120 passed unanimously in the Illinois Senate. Only one no vote prevented both measures from passing unanimous in the House as well.
HB 4023 increases the severity of assaults against sports officials to Aggravated Assault, a felony offense. Persons convicted of aggravated Assault could face as much as three years in the state penitentiary.
HB 4120 establishes a mandatory minimum fine of $1000 for battery of a sports official -- $2000 for a second or subsequent offense."
Word should get around pretty quick after the first coach or fan is forced to face this in court.
