You should call an attorney right away that does federal criminal defense work. People make the mistake all the time of thinking they can speak to the FBI, that nothing's going to happen to them. They didn't do anything wrong. Well, you know the FBI may not have the correct information and you need to find out what it is, why it is that they're investigating you. Why the want to talk to you. The attorney can act as a buffer between you and them so you're not making statements that later could incriminate you. The attorney can tell you basically whether or not it's in your best interest to speak to them. Sometimes it is. Oftentimes it's not because they're only fishing. They don't have the evidence and they think that they can get the evidence against you just by speaking to you.
