Possession on school property. Provides that it is a petty misdemeanor for a person with a permit to carry a pistol to carry on school property. An exception is made for people in motor vehicles and for placing a firearm in, or retrieving it from, the trunk of a vehicle. Provides that a violation does not subject the firearm to forfeiture. Also makes the following changes:

► Provides that, in relation to the current law prohibiting possession of dangerous weapons on school property, a person must know he or she is on school property to be guilty of the crime.

► The definition of school property is clarified and expanded, specifically including buildings under temporary school control. Also adds child care centers to the definition.

► Certain other exceptions in current law, such as having written permission from the principal, also apply and have been modified.

► Provides that a school district may not regulate firearms carried by non-students or non-employees in a manner inconsistent with this subdivision.

What would be the fine associated with this? Would it be sufficient grounds to revoke someone's carry permit and/or confiscate the firearm?

The police may not "confiscate" or "forfeit" your weapon but they may "take it" away from you as "evidence" and keep it for a long time, and jack you around whenever you ask about it.

Don't count on the "law" being consistant with your experience with the police or the court when it comes to guns.
