Yes I have. If you want out you have to answer the peremptory challenges the right way. These are a set of questions the attorneys will ask to see if your judgement will be influenced in a way to compromise your impartiality on the trial. Whatever they ask you, tell a story how that effected your life. Do not lie about what you have been through. Don't say your mother died at the hands of a crack fiend unless she really did. But, you can read about crack heads and be scared of them based on what you read. The idea is to show you are incapable of being impartial on the subject at hand.
