But, with the right pool of jurors, it can be done on the sly.
I’ve been on several juries. The last one involved a dispute between a contractor and a couple. The contractor was a rather odd and unpleasant man and there were a couple of women on the jury who were determined to punish him and “make an example” out of him. They frankly couldn’t stand him (though, to their credit, they weren’t bleeding hearts for the whining couple either).
Praise God for the “restraining force” of a pool of citizens! These ladies were buffeted by the more reasonable voices among our group that insisted it was irrelevant that the man was creepy. All that mattered was “IS HE AT FAULT?”
