It is up to a jury member to know what jury nullification is and that you have a right to do it. Suppose a man murders his kids molester in cold blood? Even if he is technically guilty the jury has the right to find him not guilty. The judge and the lawyer not only will not tell you this but give you instructions to the contrary because they do not like it.

Jury Nullification is another thing I like about the US like the second amendment.
