One more thing: Mayor Bloomberg isn't just a nanny-state socialist,

he's a friggin' idiot.
The operation was conducted as part of the Bloomberg administration’s effort to crack down on illegal gun sales nationwide.

Bloomberg said the operation cost $100,000 and came out of the NYPD's budget.
A: Bloomberg, despite your delusions you are NOT in charge of law enforcement nationwide,
B: If your little secret agents made illegal buys, I hope AZ prosecutes them. And if they can show you sent them to AZ to break the law, prosecute you as well.
C: Apparently you're under the delusion that everything in NYEffin'C is so under control that you can waste money from the PD budget, and take time away from, oh, clearing the streets and picking up the garbage and do this; every idiot in NYEffin'C who voted for you deserves what's happening to them. Problem is, the people who DIDN'T help put your conceited ass back in that chair are getting screwed, too.
