Yeh right....like people didn't notice them missing at work or at the supper table and the families ignored the jury duty notice...Even the mailman knows what that little card is.
And they just might want to write a book.
I don't know if it's the same in MO as elsewhere, but in places like Los Angeles the grand jury is made up of volunteers who serve for a set period of time. My cousin did the GJ thing in L.A. for one two-year stretch. It's not an everyday thing like a regular jury... it's usually only certain days of the week or during sessions.
The Grand Jury isn't the same as jury duty for a particular case.
