You should know that as a juror, you get to judge the validity of the law as well as the case. That means if you feel the law that the accused is being prosecuted for is egregious, you can find the accused innocent.
...however, do not breathe a word of this knowledge to anyone before you are picked or they will remove you from the pool immediately.
...if you want the whole jury pool eliminated, ask a nice, thoughtful question about "Jury nullification" while as many people as possible are within earshot.
