Jury selection question(s), legality issue, (for the legal minds)?

yes, and they are yes or no questions, meaning you have to answer them. they are kind of trick questions I would say. You cannot dismiss a case because you don't like the way the cop looks, but you do have the authority(with other jurors)to decide innocence/guilt based on the evidence. There is no such think that the judge can tell a jury what he finds beforehand. It is a trial of your peers(jury)and the body of the jury is the one deciding the fate of the plaintiff based on the evidence presented.
