Revises penalty for criminal trespassing while carrying firearm.

S 4978 increases penalties for criminal trespassing when a firearm is carried. Currently, trespassing in places like schools, research facilities, or utility property is a fourth-degree crime, while other trespasses are minor offenses. The bill makes it a more serious crime: if the trespass would normally be a fourth-degree crime, carrying a firearm elevates it to a third-degree crime; if it would be a minor offense, it becomes a fourth-degree crime. This applies to all trespassers carrying a firearm, regardless of whether they have a permit to carry a handgun.
