Because that would show a BIAS. They do this in all jury selections. They want people who will be objective, and neutral. People that say “I haven’t really thought about it, etc.”
By the process of elimination you have a jury of people who have all affirmed that they don’t think killing babies in the womb is wrong. The judge has already decided half the case for them. They will probably follow his lead and Gosnell will walk.
I can only imagine the jury instructions this judge will give. He has already determined that a kicking and screaming fetus that is outside the womb is not necessarily “alive”.
