With my past military records and Security Clearance investigations, any investigation will only have to cover a few years since my retirement.  

I've provided my fingerprints for background checks to so many government agencies over the years that the print file alone is measured in portions of an inch, much less the interviews, Standard Form 86's etc. etc.  

Throw in the investigations to be admitted to the Oregon State Bar, become a Deputy District Attorney,  work for the State of Oregon, and even get Concealed Weapons permits over the years and there is little that numerous government agencies can't pull up on me.

Heck, my first Top Secret Cryptographic Clearance interview took over three hours and I was only 18 years old!

I'm perfectly comfortable in participating in their version of a 'tip line' and any of its ramifications.
