The globe-hopping prof says his overexposed life began in 2002, when he stepped off a flight from the Netherlands and was detained at the Detroit airport. He says FBI agents later told him they'd been tipped off that he was hoarding explosives in a Florida storage unit; subsequent lie detector tests convinced them he wasn't their man. But with his frequent travel — Elahi logs more than 70,000 air miles a year exhibiting his art work and attending conferences — he figured it was only a matter of time before he got hauled in again. He might even be shipped off to Gitmo before anyone realized their mistake. The FBI agents had given him their phone number, so he decided to call before each trip; that way, they could alert the field offices. He hasn't been detained since.
