Well we do fingerprint people who have been arrested so I cannot see why a law abiding citizen who wants to obtain his rightful cc permit cannot also be printed. On the other topic I wish there was a voter ID law. The US goes around the world demanding at elections we oversee yet at home it’s wide open for fraud.
Soo... people wanting to exercise their 2A rights are equivalent to people arrested for suspicion of a crime? Just want to clarify your comparison and justification for infringement.
