Don't bother with faking anything. Just make it plain that you will not wear a mask. If they don't like it, they can waive your participation. Also, when you are being questioned for jury duty, make it plain you believe in jury nullification. This is anathema to judges and prosecuting attorneys, and it would be surprising if they would permit you to be part of a jury. Or even make it plain (as in your letter) that you regard jury duty as corrupt or dishonorable. They may have second thoughts about anyone who refuses to accept a jury verdict as legitimate. (If you happen to be an engineer, say so. It is urban wisdom that neither side will want you on the jury, because you would be less susceptible to emotional manipulation or confused logic.)
