One of my professors for my law classes, who of course was a licensed attorney herself said that it's mandatory that attorneys be barred from juries and she's been called but ruled ineligible on those grounds. In fact I think I've heard that anyone employed by a law firm is barred from jury duty due to a possible conflict of interest, though in that case non-attorneys become eligible again if they leave their job but anyone who was an attorney is barred for life. Maybe just the law in Minnesota.
I don't believe it's banned here in Michigan, but they ask if you or anyone related to you is a lawyer during the jury selection process, and I'm guessing the judge and/or lawyers would toss you off for that reason.
