I agree about not all CCW holders are good guys. I attended a gun show in Valley Forge and decided to wait outside the entrance to the show (entrance was indoors inside a hotel) and watch as people entering had to check their guns at the door (hey put plastic zip ties through the guns and let you take them into the show). Let me tell you, be afraid, be very afraid - I wouldn't trust half these guys to walk my dog let alone carry a gun.

PA is a shall issue state. Your permit means you have never been caught, nothing more.
