Terrorists are basically camwhores with guns instead of tits: they're always videotaping themselves, they desperately crave attention and rarely have anything interesting to say.
If you need proof look back to 2007, when six would-be terrorists embarked on a plan to attack the Fort Dix military base in New Jersey. Rather than practicing their covert plot, you know, covertly, they got a bunch of guns together and went down to a public shooting range with a video camera, where they proceeded to shoot at targets while screaming about their radical agenda. So now they've got their damning footage of them screaming, "WE'RE GOING TO DO TERROR! WOOOO!!!!"--but they weren't sure what to do with it (they didn't know how to get it off the camera). So to get it converted to DVD, they took it down to... oh God, really?
They took it to Circuit City.
