Held in contempt: Woman listens to MP3 player while serving on jury

I find that one of the more interesting parts of the law is any action related to “contempt of court“. The term basically covers any tomfoolery that goes on during the serious legal business of a trial, and most judges are given free will to impose punishments. Generally you don’t see people sent to county jail for more than 30 days for the offense, and that would be a serious situation indeed.

In any event, this woman was caught trying to get out of jury duty, giving lame excuses, and eventually it was discovered that she was wearing an MP3 player under her hijab. Unfortunately this sort of thing could spawn a knee-jerk reaction; especially if it occurred in the States.

I assume it could easily occur again with anyone with long hair, or a cleverly-disguised Bluetooth earbud. One might expect that jurors would have to pass through a metal detector before entering the court, although that might not find certain solid-state devices. Personally, while jury duty might suck for people, I believe that avoiding it is the sign of a self-indulgent jerk. Hell, you could always be serving in the army for your country instead.

What type of measures would you think of that could alleviate this situation? Is it more of a social conditioning angle that needs to be reviewed, or is there any technical prevention process for this sort of thing?
