This article talks about that and a bunch of other stings. An undercover cop in NYC tells someone he has an iPhone for sale and he really needs money to feed his daughter.
It's pretty sickening.

I think there's been plenty of times NYPD has baited Muslims in mosques.
And the FBI has been known to do the same thing. Cooking up terrorist plots and hoping people will join them. Ridiculous.
