Local county jury duty sucks here, they pay only if you are put on a panel and mileage reimbursement was only one way. Criminal cases are a special pain, as there is always one person who seems to think a case will be clear as a Perry Mason episode.
The one case that still bothers me that I was empaneled on a jury for was an attempted first degree murder case. It looked pretty rock solid against the defendant, but the wiley defense attorney suckered the young prosecutor into requesting a mistrial after he ventured into a line of questioning that was evidenlty prohibited before the start of the trial. The judge reluctantly granted it, then the defendant couldn't be retried due to double jeopardy. The victim's life, health and finances were ruined by the perpertrator's actions. I wonder how attorneys who pull this kind of crap sleep at night.
Federal jury duty is better, every time you have to show up, you get paid $40 plus $10 for parking. Since cases are frequently settled or postponed, the summons letter received midweek is often invalid by Friday at noon. I did a four month stretch and only had to show up twice, once to get questioned and sworn in, the other time was for an immigration fraud case, I was part of the group that was eventually dismissed. Both times I barely missed any work, so I returned to work the same morning and pocketed the money, since as a a salaried employee, I had put in far too many unpaid extra hours over the years.
