In Texas, Louisiana and Mississippi, it is now a federal crime to state orally or in writing to any federal administrative or law enforcement officer, during the course of an official investigation that you don't know what they are talking about if in fact you do. So if, for instance, you are a user on an anonymous bulletin board and you are asked if you are "X" when in fact you *are* X and you deny it, you can get a couple of years for that, even if you are not the subject of the investigation or guilty of any criminal activity--in theory, at least. This also pertains to any other kind of investigation: tax, environmental, drugs, antitrust, armed carjacking, international weapons trafficking, or anything else coming under federal jurisdiction. Mike Godwin stated that the FBI agent said something like " "we can lie to you, but you can't lie to us." That has always been true under 18 U.S.C. 1001. But now you can't even answer one of their questions with a "no" if the truthful answer would be "yes." You should read up on this, it's scarier than Clipper and the digital telephony proposal combined.
