I missed jury duty twice in Brooklyn ,now they send me letter that I need to show up for non compliance or else can charge me fine/imprisonment .need to take it serious??
Technically, you can claim ignorance until you get a letter via registered mail. CMIIW.
Realistically, the best option is to show up late.
If you come before (IIRC) 10:00 they will still accept you for the day, but most jury selections happen far before then.
When I went, they only had 3 selection the entire time from 10 to the end.
And those selections are usually to choose "Alternates" to the actual jury, so they only need 2 or 3 of the people they pull in, so it shouldn't be too hard to not get chosen.
