For those seriously wondering, yes, in the U.S justice system, many celebrities have been on jury duty, as well as several politicians. Unfortunately, fictional characters aren’t typically allowed jury duty, meaning that you’ll never get a Quintesson to give you “Innocent” before throwing you into a vat of Sharkticons.
In my jurisdiction the only ones formally exempted from jury duty are those who are employed in the courtrooms: judges, bailiffs, and court reporters.
There are several other occupations that, while not formally exempt, are almost guaranteed to result in you not being picked: law enforcement, child protective services, district attorney office, criminal defense attorney.
But you could still be asked to serve if the case was civil and did not involve cops. There are many reasons you can be dismissed, but it varies wildly from one case to the next.
That was probably because they brokered a deal between prosecution and defense, and the jury was not needed. You’re supposed to check the website in the morning to make sure you’re needed. You probably just got very very lucky.
I want to say this was before everything was fully online, but it's been so long that I have no idea. I still find it odd that I haven't heard a peep since (not that I'm complaining).
