I don't actually have much of a problem with this. Lying to a suspect as part of an investigation isn't infringing anyone's civil liberties, unless they lie about specific things, such as telling a suspect lies about their rights.
I thought it was well known that the police can lie as part of their investigation. Perhaps people thought there was a limit to the lie: they're OK with "your accomplice already spilled the beans and we already know everything" but not OK with "hey I'm a reporter doing an interview." But how do they think the FBI poses as arms dealers, terrorist recruiters, drug dealers, corrupt lobbyists, etc. without lying about it?
It depends on how certain you are that someone is a suspect. If you just get to go around doing anything to a person because the FBI put him on a list, that's sort of a slippery slope, in my opinion.
But I didn't say they could do anything to a person- I said they could lie to them. It doesn't matter how sure you are that someone is a suspect for something like this, because nobody's rights are being infringed.
