Why Would a Bosnian Dude Strap a Fake Bomb on His Chest Knowing He'd Be Stopped By Airport Security?

That's the question I asked myself as I read this:

Jacksonville International Airport in Florida was closed for six hours after a man going through security told a checker that he had a bomb hidden inside his camouflage backpack, authorities said Wednesday.

The man, Zeljko Causevic, was charged with having a hoax bomb. He told authorities that the device — a luggage scale with two batteries and a microchip, plus a remote “detonator” — was “supposed to be a bomb, but it’s not."... 

Causevic was scheduled to appear in bond court in Jacksonville Wednesday afternoon. An arrest report indicates he is originally from Bosnia.

Is the guys nuts? Or is there (jihadi) method to his apparent madness?
