In California, juries get no respect. They can listen to all the evidence, deliberate with the best of intentions, and still be accused of being "incredibly stupid" if they don't reach the result the prosecution wanted.
It's why California jurors are well advised to read Low Culture's "Guide to Jury Duty," which contains a number of helpful tips like these:
[M]ake sure you've drunk something—preferably a strong, alcoholic beverage—before the proceedings begin. It will lend a festive air to the entire affair, which is good, since you will probably want to kill yourself the moment you arrive 'till several weeks later when the details of the case will come back to you in nightmares. (But in your nightmare, the killer will be your dad: Don't ask us, we're not shrinks.)
Don't bring a book or a magazine unless you want your fellow jurors to think of you as some sort of snob. Furthermore, displaying the ability to read will lead directly to the court officers not selecting you for trial. Best to show up with a lot of photos of your cats or your grandchildren, the better to facilitate conversations with those around you. If you must bring a book, bring a Bible: Everyone loves talking about the Bible with strangers.
