I was on a murder trial about 15 years ago. So many people tried to get out of it by telling the judge "I can't be impartial because I don't like guns".

Every time, the judge said "so are you telling me you would convict someone of murder, that you don't think murdered anyone, just because you don't like guns?" Most people said no. Some would squirm and get squirrely and the judge would follow up with "you would ruin an innocent person's life just because you don't like guns?"

No one said yes, despite them obviously wanting to. She did a good job of calling them on their bullshit.
