I mean, have you received a summons (letter) from the courts telling you that you’re selected to be a juror. You show up to the courts and assigned a number along with being asked about occupation, status or whether you know anything related to the case in question & etc. but is the probability on becoming part of the 12 jurors that high? Is it also a criminal offense for failing to show up?
Failing to show up is punishable by up to 6 months in prison. The reason I know this because my ex was once called for jury duty and every single time they brought it up they insisted on mentioning the potential consequence of not showing up. Every single time. They had very high anxiety about this.
