Here's a travesty of justice:
Dear Jury Foreman (Forewoman?) It's legal to dispense Marijuana in California, because California says it is. The judges, and the federal prosecutors, are lying to you. How do you find the defendant not guilty? You disregard the instructions from the judge and determine the rightness of the application of the law in this case (as described here) and then you state, The Defendant is Not Guilty.
...it's actually quite easy, but good luck being seated on a jury if you admit to having even heard the acronym FIJA.
