Snitches are a panacea for the government. They made everything easy, gave them access to "evidence" that served any purpose they wanted and facilitated the arrest and conviction of any target of their choosing. And they never had to leave the office.
So there they sat, munching donuts and making threats, as they scared the daylights out some poor schmuck, who then flipped to serve their new master, the Department of Justice. Ah, the good life. For federal agents and prosecutors, at least.
But when the government wanted a few American Muslim men to become their bitches snitches, something very wrong happened. They refused. Refused?!? Nobody refuses the demands of the government, so they had to be taught a lesson.
