There's too much search engine garbage to find an original source, but PhDs, scientists, physicians, and attorneys (of course) are basically disqualified from jury duty.
Funny how demonstrating that you're able to think for yourself with a degree disqualifies you.
I'm a nurse and was on a murder jury trial with a sheriff deputy. They're not allowed to ask your profession in voir dire. What you cannot do is provide expert testimony as a juror in deliberation. You are, of course, expected to use your experiences in your decision.
They don't want someone to start adding context or outside information during the jury deliberation. If you do, then the defense has no opportunity to argue against you.
They don't want any additional discussion that could sway the case unfairly one way or the other.
No, you are supposed to be able to put up a defense.
Who's to say the jury is correct? What if the specialist made an assumption that was wrong, shared it with the jury, and found a person guilty because they trusted this expert. Now you have no way of challenging this, and rebutting the assumption.
You DON'T want those "independent thinker" jurors you need them to only consider what's been presented in the case. It's the only way it can be fair.
I've got two jury duty summons so far and haven't even made it to any form of interview. It may be due to my age at the times, but my job pays me for jury duty so I'll gladly do my duty.
If Trump and his team could dream it up in far less than a month, mere mortals will be able to follow it. It's not really all that complex. Just f*** over the election counting process in a variety of ways.
