Go figure, working at the IRS can make a person snap.

46-year-old Roland Moore of Tewksbury, Massachusetts works in customer service for the IRS, so you can imagine what his day-to-day life is like.

And the police got a call last week from a Homeland Security agent who said Roland had an illegal stash of guns.

So the cops went to check him out, and when Roland answered the door — he was wearing a tin foil hat

They found four guns in his house and they were illegal, since his firearms license was suspended six years ago after he was busted for assault.

He was arrested and he’s getting a mental health evaluation for the whole tin foil hat thing.
