Sounds like a rectal-cranial inversion. Possibly a S.E.P. field (somebody else's problem) in effect as well.

Kinda like the guy I had to support the first day I was at the EPA. Found a cache of porn on his hard drive - at least, I'm pretty certain it was porn. All I did was look at the filenames, didn't bother to check, since he was standing right there, and I wasn't interested in getting in a brawl with somebody on my first day.

Reported in to my manager, they went back up, and he proclaimed total innocence to it being there.

This despite working from an office with a lock, and he had the only key.

Still, it's a testament to the skill of the federal employees union that he didn't get canned...
