re: True, an SSBI doesn't reach back far enough,
If you knew anything about what your saying you wouldn't call them 'security clearances' - which they are not. They are access authorizations. And if you have ever had a polygraph probe you would also realize that they are never 'creative' they are strictly scripted and agreed on before the test is taken.
My evaluation is that your as full of crap as a Christmas pig.
