What are 'peremptory challenges'?

Iloilo Jones (Executive Director of Fully Informed Jury Association) gives expert video advice on: What is 'voir dire'?; What kind of questions will I be asked as a juror?; Why do I have to answer personal questions before I'm chosen for jury duty? and more...

A peremptory challenge means that they don't have to give any reason. They don't even have to ask you any questions. They can just look at you as say, "Thank you for coming. You're dismissed." And they may do that because you look impatient, angry, because they know by looking at you, you're the wrong age, the wrong color, and the wrong sex. That you don't fit the profile of jurors they want. And they can't be called on that. The other person doesn't get a chance to ask you questions. You're just dismissed.
