Lol, I'm sure the mafia would *love* it if narcs were legally bound to disclose their narcness when asked. I mean, then all the mafia would have to do to find the narcs in their midst is...ask them. Heh, that's so totally not true. Cops can and do lie all the time; they're *trained* to lie, and to lie convincingly. Never believe anything a cop says, especially if they are trying to interrogate you.
