This is why a Fully Informed Jury is so essential to restrain a government that has exceeded its limits as well as to insure that the guilty are punished while the innocent go free.
The jury has the right and duty to judge both the fact and the law, no matter what the judge tells you.
The jury is the last line of defense against an unjust law.
Of course it has almost gotten to the point that the jury is as much a part of the government as the judge and prosecutor. In the last several juries I've served on, more than half of the jurors worked for government (federal, state, local). I keep seeing the same faces over and over again too. It's almost like we've become professional jurors.
