Stupid State Laws - Pennsylvania 5

Here comes another post about a state law that still exists on the books and why it is ridiculous (to see them all, click here):

Pennsylvania

"Fireworks stores may not sell fireworks to Pennsylvania residents."

Really Pennsylvania?  This makes no sense.  Do you have fireworks stores in your state but refuse to sell fireworks to your own residents?  Or is it that you don't have fireworks stores and refuse your residents from going to other states and buying fireworks?  Because if it is the second one, how in the hell do you expect to enforce that?  Do you have have Pennsylvanian cops in other states (outside of their jurisdiction I might add) stopping state residents from buying fireworks?  You do realize that that is ridiculous and illegal?  Wouldn't it have been a lot easier to just outlaw fireworks in Pennsylvania?  I guess not.  Or is it that you needed extra revenue in the state, so you allow fireworks stores, but just not the actual selling of fireworks to state residents?  I'm more confused than when I started.

"Hahaha, try and stop me coppers!"
