> Spoken like a true trial lawyer !
You have the knowledge, and resources to defend yourself. (Of course, I am sure you know what they say about lawyers who represent themselves ....)
Of course they can't prove actual knowledge, and probably lots of other defense if a Court tried to enforce a jury summons,....but fighting something like that involves hiring a lawyer and takes time and money. I'd also caution against generalizations about what one jurisdiction might or might not due -- the following is a excerpt from my State's judicial system website:
What if I fail to appear for jury service?
If you received a juror summons and failed to appear, you can be fined, incarcerated, or both.
I'm not saying I've heard of anyone being prosecuted for a one time offense, but why take the chance. Better to handle it the proper way than simply thumbing your nose at the system.
