Here, where I live, it would be real easy to avoid jury duty if one wanted to. The notice for jury duty in my county is mailed in a very distinct style of mailer. It's would be very easy to just throw it away and, if they come after you, you can say that you never received it in the mail. There's no way for them to prove you wrong because you don't have to sign for it or use any other method to prove otherwise.
