However, usually the attorneys are good at picking though jurors. Sometimes their not. Which allowed me onto a jury, even though I had graduated from law school and taken the bar, knew friends in the Public Defender's office, had done three months of probono work with Federal Defenders.
You can never tell. But it's up to you and how comfortable you are with the situation you will put yourself in. As long as you truthfully answer any question put to you during voir dire, no hassles. I wouldn't suggest misleading folks just to try to nullify, though.
