Heh, nice. Seems almost 50ies-era commie hunt-esque. If it wasn't so incredibly over-used and tired, even a reference to George Orwell could be used in describing the logic behind this saga.
Step 1) target people who are dicks/deviants, but generally minding their own buisness/harmlessly stupid
Step 2) introduce them to crime and encourage them to get even more involved in extremist circles
Step 3) provide them with ideas on what crimes to go commit
Step 4) provide them with the means to commit said crimes
Step 5) continue encouraging them every step of the way and ensure nothing happens to make them think this is a bad idea
Step 6) at the last second, spring your trap! Hold up these obviously born criminals as an example on why no-one is safe and the state needs further powers to screw with people.
I'm not one to start bitching about state powers, but this is an obvious abuse of it. They were probably dicks, but so is just about every person I've met at any religious function I've been forced to attend in the last 2 decades. Put the kind of effort into it that the FBI has done and you could probably get 2/3rds of the people you meet in the streets to commit a terrorist act, given time. Peer pressure is one hell of a powerful thing, and taking advantage of socially isolated morons is child's play for anyone who has resources and knows what they're doing.
Might as well have targeted a bunch of 10 year olds.
To clarify, I have no issues with agents infiltrating extremist groups. But infiltrating with the aim of escalating their behaviour enough to arrest them? Fuck no, there's something seriously wrong with someone's mission statements goin' on there.
