Yes.
Several years ago. On a Felony trial.
We sat there and listened to the lawyers lie back and forth, and the witnesses mumble and stammer, and some experts present evidence, and on the fourth day the judge cleared the court room and we sat in the jury room, not talking, drinking lousy coffee, and waiting.
In the end, the guy took a plea, and they sent us home without even a thank you.
Counting Jury Selection and all that, plus sitting in the jury room while both sides made pre-trial motions and all that crap, I missed TWO WEEKS of work, had to pay for parking and my own lunches, for nothing.
Remember, while you are on the jury you're not supposed to talk to anybody, read a paper, watch ANY TV (because there may be a newsbreak during the Price is Right and you'll see something about the trial), listen to the radio, nothing, you are supposed to live in a vacuum.
I've been called for 'jury duty' several times, but that's the only trial I've been on.
In my opinion, in the American Criminal Justice System, it is those on the Juries that come up on the short end of the stick. For the most part, they're ignored and treated like cattle.
