I did an inquest.
At first I was bored, couldn't care less. By the end, I gave a shit and realised I was surrounded in the jury by "mostly" decent people who also cared.
It was a painful experience but once you're there there's nothing you can do about it so at least have the decency to take it seriously (not necessarily suggesting you won't). It's easy to just give in and agree to get the deliberation over quickly, we had a couple of numbskulls filling up an bourbons, moaning and willing to agree with whatever needed to be said just to get out of there. Forgetting that there's a family in the next room who want to know whether or not their son committed suicide in jail, what contributed and whether more could be done to prevent it… it was quite a distressing but ultimately fulfilling experience.
I was surprised by how annoyed I was when the local paper then reported a completely different verdict to what we came to!!!
