ironglow: I doubt it. Streets and roads are public property and you are legal there. Schools, although public property, are exempt from that definition only under the gun free school zone law. It just means that you cannot carry your gun legally on school property.
That being said, I think the law is foolish. In the few situations I have read about where some responsible adult with a gun has stopped or prevented school shootings it was the actions of those responsible private ccw citizens who have prevented a tragedy whether they violated a law or not.
I also find it interesting that wherever legal carry is not allowed by private citizens, the police do have the authority and we know that in New York State, a private citizen goes through a more intensive background scruity and personal history check than do police candidates. Go figure, huh? Just my two cents worth. Mikey.
