Just go, if they ask if you can serve, tell them yes, and that you can shoot someone who is guilty from a mile away. You will be sent home shortly after.
You can get out of it the first time and delay it a year for no reason... you can pick up a felony (I'm a felon and they called me for jury duty) if it is a civil case I can still be on the jury but just blurt out some bias stuff or lie...
1. Say you never received the letter
2. If you do go, have a biased opinion on the subject of the case( if its domestic violence say your all for it, even though i pray your not)
3. Pretend to be the worst citizen in the history of mankind
