To reiterate: if given a summons by the court, in person attendance is mandatory (applies to all 50 states). After voir dire, if either the lawyer or judge has selected you as the juror and being presented with evidence relevant to the case: what types of cases were you assigned whilst being a part of the jury?
Also, what happens if the individual fails to willingly show up (non-excusals) in court on the appointed date when they’ve been handed a summons in the US? For reference, in my country where Jury Duty also exists: the offense for failing to show up in person incurs the equivalent of an ~800 USD fine.
I got called for the penalty phase of a capital murder. (death penalty).
The parties settled before anyone was selected. It took 2 days. I found out later that the convict was already on death row, but had gotten a re-trial because of a recent SCOTUS ruling. I was in no danger of being impaneled.
