I did not provide my SSN for a purchase about two months ago (fortunately I am not yet required to buy a gun every month), just leaving the form blank where one was requested, and the transaction went off without a hitch.
However, my real name is not common at all so PSP's database can easily identify me. I can see where someone named John Smith or Jose Garcia would have difficulty distinguishing themselves from criminal types with a similar name and birthdate.
Anyways, I thank you for your efforts to make PSP comply with privacy issues but it is my opinion that these background checks are unconstitutional on the face of it. The state does not have authority to place prior restraint on the exercise of a right.
