Wow.
My CCW class (in Michigan) had a two hour session conducted by a local lawyer who knew the federal, state and, as far as they went, local laws and regulations pertaining to both concealed carry and general firearms use. He provided a handout that was a photocopy of the actual laws and, of course, his card. One point was driven home: if you are going to carry, at the very least have a lawyer who knows handgun laws in your personal phone book; if you ever have to pull the trigger, call law enforcement first and the lawyer second, and don't answer any questions until he gets there.
Also, when I applied for the permit the County Clerk provided another printout of the up to date state laws and regulations. Not the most fun reading, and frankly, having a lawyer turn it into understandable text was very useful.
I'm really surprised PA didn't provide at least some information on what the laws are. That borders on irresponsible.
