I got called for jury duty today and learned quite a bit about how it works:
They start from a pool of about 500k eligible Wake County citizens and a computer chooses 500 potential jurors for each day. Then an algorithm randomly assigns a number to each juror. My number was 83.
The day before your jury day, you call and listen to a recording with instructions. Today all jurors with numbers 1-99 had to appear and numbers 100+ did not.
If you appear, that counts as having served jury duty even if they don't use you in a jury. That means you won't get called for at least another two years! Woohoo!
Oh, and they pay you $12 per day. Cha-ching!
