At one point, ADA Carmichael stated that Bail Agent Difka had been dishonorably discharged from the Marines. ATF Form 4473, Firearms transaction Record, Section 11g, asks "Have you been discharged from the Armed Forces under dishonorable conditions". A yes answer would preclude Difka from ever owning a firearm. While he could still be a bounty hunter (eg: Dog, the Bounty Hunter) he would have not been allowed to carry a gun.
