What you say is true (his own experience can influence his vote) but that's not the relevant point. What is relevant is that he did not disclose his personal experience in selection, and then he attempted to persuade other jurors based on it.
Well said.
The jury selection process helps lawyers and judges. Does it help everyone else?
Trials take longer
Citizens that aren’t selected waste their time
Do we really get better juries and verdicts by excluding knowledgeable citizens?
Do we not have 12 persons on a jury so that there is a reasonable expectation that one’s peers are represented?
