I think Jefferson Parish just sends it by standard mail and if you did not send the card back you were not put on the list for the day you were suppose to serve. Those days may have changed but if you don't want to serve I can't see how they can punish you for not wanting to do it? Anyone ever skip Jury Duty? Do they come and kick your door down if you don't show up? Serve a bench warrant? I would think the D.A. and clerk of court have better things to do than going after people who do not show up for jury duty.
