The Fifth Amendment right against self-incrimination does not attach until the initiation of formal adversarial proceedings. You do that, you will get a one-way ticket to join Scooter. You cannot assert the Fifth Amendment if the FBI just wants to talk to you, or if the Grand Jury desires your testimony. The Grand Jury is entitled to every man's testimony.
"You cannot assert the Fifth Amendment if the FBI just wants to talk to you, or if the Grand Jury desires your testimony. The Grand Jury is entitled to every man's testimony."
Well, sort of. You can tell the FBI to go to hell. Like I posted earlier, name, address, I want my lawyer here's his name. The Grand Jury is a bit different, but the 5th Amendment protection still applies unless you're given at least some sort of immunity. You of course may find yourself a target after the assertion, however, or be held in contempt.
I would disagree with you. The words are: "nor shall be compelled in any criminal case to be a witness against himself,...without due process of law."
As soon as they offer me immunity, then I'll speak.
Also, it is too easy to simply call one's memory into question throughout any statements and regularly affirm that you reserve the right to change anything in any way as your memory is refreshed.
