ONE TOURIST VISA PLEASE

"If we can't catch a Nigerian with a powerful explosive powder in his… underpants and a syringe full of acid, a man whose own father had alerted the US embassy in Nigeria, a traveller whose ticket was paid for in cash and who didn't check bags, whose visa renewal had been denied by the British, who had studied Arabic in al-Qaeda sanctuary Yemen, whose name was on a counterterrorism watch list, who can we catch?"
Maureen Dowd, NY Times

This is who the US State Department issues multiple entry tourist visas to.
