Getting harder to stack juries

Did these people know about jury nullification? Or did they answer as they did so that they could get out of having to be on the jury?

If people are waking up to the power they legally have in jury nullification, how long will it take before Government and the courts try to hold jurors in contempt for doing the thing that they have the legal right and duty to do? Could this whole thing be signalling the end of the jury? Are we headed for Judge Dredd after all?

Finally, some good news.
