> You can’t trust a jury of 12 people in a handpicked jurisdiction, where evidence is carefully screened by lawyers and judges, to make such consequential decisions for the whole country.

Then it sounds like you need to amend the Constitution. Because that's how our system works. You are indicted by a grand jury in the jurisdiction in which you are accused of a crime and then you are put in front of a petit jury. Both sides agree on who the jury is.

I'm struggling to understand the alternative system you're imagining.
