True. However, there are a few rules:
Never discuss the subject with anyone when on a jury or under an active jury summons.
Never discuss the subject with any government employee, ever.
I’ve sat on two juries, both in the mid-1980’s. When we were sent off to deliberate, I let the rest of the jurors know that since the only prying the court can do into any juror’s vote on the verdict is to ask if it is their vote. And that they could basically vote in favor of one side or the other because they didn’t like someone’s hair color, regardless of any judges “instructions”.
Never discuss the subject with anyone when on a jury or under an active jury summons.
Never discuss the subject with any government employee, ever.
Your advice is accurate and true, I have read it in Jury Nullification pamphlets, but it sounds like the kind of advice one Soviet citizen whispered to another. It's legal and Constitutional but don't let the government hear you say it.
