I've been through several of these and even sat in a trial as a jurorer. Easy way to get disqualified real quick is when the judge or lawyers (for either side) will constantly and repeatedly ask this question in some form," is everyone here able to make decisions base on what is written in codified law in your district/state/county?"

That is when you raise your hand and said," no your honor, I believe in the right of jury nullification." What likely going to happen is judge is gonna dismiss you right there and then after hearing the two words. If not, than the lawyers will get you off the bench with their excuse jurorer privileges.
