[Evolution]

My company has the following policy:

Carrying a firearm and/or weapon onto Company property in violation of this Policy will be considered an act of criminal trespass and will be grounds for immediate removal from the Company property, and may cause the Company to refer the matter to the state and/or local police.

Can they actually charge you with criminal trespass if your have a valid permit in Pennsylvania without asking you to leave? I was under the assumption that it isn't tresspasing until you refuse to leave the premises. I am under the impresion that no policy is above state law. I was told on another forum that they could basically charge me with whatever they want to...

Thoughts?
