Quoted:
As far as the background investigation goes, I for one had to get a secret clearance in order to work on aircraft, so my background investigation was a little more indepth than just your average Marine. Every Marine in aviation has to get that background check. 3 of the 4 worked in aviation. One of them was in Avionics so his background was screened even more. I think the underlying issue is the pack mentality. You get the wrong crowd together and you are going to get bad situations such as this.
A secret clearance involves nothing more than a NCIS/10 finger check. A SSBI is the full Monty. I had a SSBI when I started helping various agencies on terrorism finance investigations which ultimately resulted in a TS/SCI clearance level. BFD right?
Single Scope Back Ground Investigation is where they do all the diggin in to background, providing references, credit and finances check, relationships with foriegn nationals and organizations. The expedited it and it still took awhile and in the meantime I had a temp clearance. lol.
Secret Clearance is something everyone had in the military until the Walker trial and they came around and administratively reduced our clearance levels.
They also have
Personnel Reliability Program in the military for dudes that had nuke training in artillery and stuff. that is probably what you had. That is the NCIS/fingerprints plus a health records check.
Ultimately a background check is looking for 2 things moral standing and blackmail ability.
I'd like to point out what they told me at the George Herbert Walker Center for Intelligence (Langley).
The only folks that give up really damning secrets are those with clearances. In other words clearances don't really mean shit and if you are a dirtbag you are a dirtbag.
