Entrapment

Telling guys like this that you're "'Brother Mohammed' from al-Qaida" who's going to help them blow up the Sears Tower and then convicting them of conspiracy to commit terrorism is like sending a 17 year-old cheerleader to an SCA convention in skimpy medieval garb and having her tell some hairy, fat, insane guys that she wants to fuck them and then convicting them of conspiracy to commit statutory rape.
