Jury Duty

I had jury duty this week. I was not picked or even questioned. But the process left me with a few questions.

During the question and answer perior, the voir dire, three potential jurors were dismissed because they could not understand English. They were so inept in their English skills that when the judge dismisse them they just stood there until somebody translated what was said.

Prospective jurors are selected at random from the list of registered voters. In order to be a registered voter you have to be a U.S. citizen. How did these prospective jurors make it? Were they faking their lack of English skill to get out of jury duty? Why did the judge not question them on it?

It all made me wonder.
