FBI issues warning to Congressman.

That's what this article should have been titled.

The new chief of the FBI's Criminal Division, which is swamped with public corruption cases, says the bureau is ramping up its ability to catch crooked politicians and might run an undercover sting on Congress.

Did you hear that, Mr. Congressman? We're going to conduct stings.

I mean, what the hell is this? When they run a sting on the mafia, do they call ahead and say "we're going to be conducting undercover stings, Mr. Corleone"?

Unbelievable.
