Once in a while people do forget the have the gun. 

ATLANTA (AP)Clayton County plans to crack down on passengers at Atlanta’s airport who brings guns to the security checkpoints.
Clayton Solicitor General Tasha Mosley says that anyone caught with a firearm in airport security checks can forget about ever getting the gun back. She said confiscated weapons will be destroyed under a new policy.
Authorities say 62 travelers arrested so far this year have been charged with bringing guns through security. Offenders have included business executives, students and a former assistant district attorney.
Passengers are booked into the Clayton County Jail for at least an overnight stay if a weapon is confiscated.
Many passengers have said they didn’t intend to break any laws, and forgot that a gun was in a bag or a briefcase.
