The constitution does not provide for instruction of juries. Juries do sit in judgement first of the law, and second of the defendant. A jury that has been instructed is invalid.
LOLOLOL!
Wow.
Juries "sit in judgement...of the law"??? Really? Show me THAT one in the Constitution. Odd that it does provide for superior courts to do exactly that: sit in judgment of the law. If that's the jury's job, why would the Constitution provide for superior courts, up to and including the SCOTUS?
You live in a bizarre fantasy world, FRiend. Pray you never sit as a defendant with a jury who shares your beliefs. The sword cuts both ways.
The jury is the superior court; the judge is merely a proctor.
