Just say NO! Jurors have the power of jury nullification but the court and attorneys will never tell them this fact. If a juror feels, for example that marijuana should be legal, then the state has no power to take any action against them if they refuse to vote for a guilty verdict in a marijuana possession case. I believe jurors should use their power more often against unjust laws and wrongful prosecutions.
