The crime she was convicted of was proclaiming her innocence on a matter she was never charged with.
She was never charge with insider trading; she never committed perjury.
Are you telling me that it is now a felony in America for a person being questioned by the police to assert their innocence?
No, but it was, and continues to be, a federal crime to lie to FBI agents. She did so. End of story.
Look, I readily concede that this has all turned out to be a circus. But don't insult our intelligence by understating the case, either. She did not simply "assert her innocence." She did far more than that. The 5th Amendment does not give you the right actively hamper an investigation, it only gives you the right to do nothing to help.
