> you're saying the Federal Bureau of Investigation is a criminal organisation
No. What I said was that Hoover was a criminal, and that his reign at the FBI was marked by illegality. Whether or not the present FBI is a criminal organization is a separate claim that I'm not going to make right now.
> And this doesn't come up in every single news article about the FBI? This doesn't come up to discredit every single piece of FBI evidence in court?
It's an established fact about the FBI, the same way that the Tuskegee Experiment is an established fact about the CDC. Both agencies (claim to) have reformed, so there's nothing to "bring up" in court.
The fact that you don't personally know about it doesn't mean it's ignored. It's taught in US high schools as a critical part of America's cold war hysteria as well as the federal government's reaction to the civil rights movement.
> Tragically what "Many Americans" believe means nothing about credibility.
You asked specifically whether Americans hold Hoover in contempt, not for the factual content of their beliefs. I think that they're right to hate him, but the base factuality of their beliefs doesn't change the fact that his public image is negative.
