At my last duty station I had an Airman reporting to me that had been incarcerated in the USAF Correctional Custody high rise facility at Lowry AFB. He had been in a theft ring stealing test equipment and fire extinguishers, etc. and sending them back home to his family to sell. As his Supervisor I was told. No one else in the workstation knew unless he told them. I was actually shocked to find out about it because we all held Top Secret Security Clearances. My only answer for that was that it was Jimmy Carter's Air Force.
It must have been different then. When I was in during the 80’ and early 90’s you would have had your clearance pulled. Even if it was only an allegation.
My ex-wife had a difficult time getting a clearance because she was born in Japan. Her dad was in the Air Force and stationed there. Go figure.
