Fingerprints, references, employment information, disclosing medical records, the involvement of judges and police. It's all BS to discourage people from going through the process. A background check to buy and maybe a course that covers defensive use and relevant state laws on the use of deadly force for people who want to carry should be more than enough to satisfy the anti-gun whiners. There is no process that can prevent all dangerous people from legally obtaining guns without banning them completely (see Jiverly Wong), which is not going to happen and certainly wouldn't completely prevent anybody from obtaining one illegally. Exercising a right shouldn't be a burdensome process that is more difficult to complete and subject to more bureaucratic whims than a license to drive.
