Jury Nullification seems to get bandied about a lot on tech sites. Yet in practice it is not as easy as one suspects, nor does it happen with any real frequency. It is common that defense attorneys are not allowed to instruct a jury to seek nullification, juries are regularly advised to apply the law in a case, and then there are courts which will screen out prospective jurors if they voice the opinion they don't agree with the law.
Then to top it off, you have to get all members of the jury to agree to it. With that you run up against morals and predispositions of the various jurors. It would have to be a pretty damn extreme law, one unfavorable with the public as a whole, to get caught up by a nullification and you can be the authorities would do their best to stack the deck
Why do you have to get the rest of the jury to agree with it? Isn't it sufficient to have eleven people wanting to convict based off of law, and one person voting no (and sticking to it) because of disagreeing with the law?
