"So let's review," the alert continued. "Floyd Prozanski's background check bill requires that when you give a gun to your best friend, or your cousin, or your uncle, that the State Police record the recipient's name, address, sex, (and social security number if they choose to give it) and the make, model, caliber and serial number of the gun!

It's already illegal for a criminal to have a gun, so they don't care whether it is registered to them or not.
