Serving on a jury is a great honor and the last stronghold of the people in terms of keeping dangerous people from the streets and keeping government in check.
You will probably be told the exact opposite of this but they are lying...
As a juror you are there with the authority to judge the individual as well as the law. The law is being judged as much as the person is.
As a juror it only takes one person who decides that the law goes to far to bring a hung jury and the law is, in this case, nullified.
It is a juror's right and duty to know and exercise the full extent of his authority as a juror.
