Lawyers always do. Often some in-depth examination of potential jurors. At the least, they move to exclude jurors who look or sound in a way that they would prefer not to have on the Jury.
I myself was excluded. The question, could you follow the instructions of the Judge. My reply, I donāt know, what are the instructions? When asked to clarify my answer, I explained that I was familiar with the teachings of St. Augustine and the principle of Just Laws, and the unwritten but vitally important duty of the Jury to determine if a law is unjust, or unjustly applied. I would not agree to turn off my brain and become a robot who says if A happened you must find B.
Judging from what I saw, the Defense loved the idea of me being on the Jury, the Prosecution didnāt even ask, the Judge excused me on the spot. I went home, and wasnāt called again during the time period. I havenāt gotten a summons since.
However, both the prosecution and the defense get a certain number of strikes, and an unlimited number of objections. They donāt want experts on the jury. If you have a lot of experience shooting, they donāt want you on the jury if firearms are an integral part of the testimony. You might believe that the Prosecution or Defense is wrong, and you might be wrong, yourself. You might taint the jury pool with an old wives tale about firearms. The good Lord knows that there are more superstitious beliefs about firearms than there are universally acknowledged truths.
