Was he asked about that during jury selection?
Was he obligated to offer that information?
So, no police officer or lawyer of any kind should ever be allowed on a jury due to their “inside knowledge” and, perhaps, any bias they may have? For a long time, if you got called to jury duty and they found out someone was the police, it was an automatic...adios. Not so much anymore.
I got out of my only jury duty because I grew up next to the arresting officer
Besides, he was a bully and an a$$hole even after we graduated
If it was on the questionnaire, he was obligated to reveal it. It wouldn’t automatically have him dismissed for cause, but the defense probably would have used a peremptory strike if they couldn’t get him dismissed for cause. Based on the nature of the charges, not having that on the questionnaire would be malpractice by the defense, in my opinion.
