Crime Doesn't Pay - Rotten Tomatoes
Political and religious philosophies aside, most evildoers would likely balk at the thought of any crime that specifically requires the death of its perpetrator. Most evildoers, however, don't exhibit the balls, the religious conviction, or the outright stupidity (your choice) of the would-be suicide bombers in Four Lions. It's difficult to strike fear in the hearts of men when your leader is personally responsible for accidentally destroying the jihadist training camp he volunteered for, when a member of your cell trains crows to be suicide bombers, and when your primary mode of communication is a children's social network where you can pimp out your bird avatar. The only security threat these guys pose is to themselves.
