I served once. I thought it was my duty. As others have said, I would want people like me on the jury if I was on trial.
It was a bad car accident that resulted in one death and one terrible injury. I was impressed with the testimonies of the LE professionals and the technical experts. It was pretty clear alcohol and excessive speed were involved.
There were 12 jurors plus a spare who sat through the trial, so when time for deliberations came, one had to be dismissed. My number came up randomly, so out I went. I was sorry that I went that far then had to go, but at least the driver's fate was out of my hands. Got a call at home that night that the verdict was guilty. Never did learn the sentence.
I would do it again, no doubt.
Related story: My Dad got a jury summons for a federal case. Seems a couple of guys got stopped on the freeway and had their car searched not far from his farm. The car had a large amount of contraband, (cocaine, I think). So they were charged with transporting it from city to city, across state lines.
The trial was going to take place in Detroit, (change of venue maybe? Pretty obvious what the verdict would be in rural America). So Dad had to drive up to Detroit.
Dad said they asked him if he could be impartial. He said yes, he could listen to the evidence and render a fair verdict. Well, the defense booted him. He believed they didn't want an old retired farmer on the jury.
