Which is irrelevant to the point I think is being made. People sometimes believe this, and if the facts can be twisted to put you in front of a jury as a defendant, it's not good for you. Whether this statement would cause a mistrial doesn't help you if it's stated to some non-involved party twenty years later and you've already served your time, or even if you are still in prison and the person saying and the person hearing that statement have no incentive to notify someone who can and will do something about it.

Too true. I know a person who said that, but I don't know which state, which county, when, or what they served as juror. Are the accused still in prison, or have they served time and done?

And it's hear-say. I have no recording of what they said.

But still, miscarriage of justice is still done. And with numbers showing federal cases end up in the +95% conviction, sure seems the quote is the majority thought. Even if it is completely wrong.
