Okay, I got unlazy for a second;
9-11.121 - Venue Limitations
A case should not be presented to a grand jury in a district unless venue for the offense lies in that district.
The difference between "should" and "shall," and "may," are very important in lawyer-speak.
I don't mind if you think YOU can get hauled off to Utah, or New Jersey of Alabama, at the prosecution whim of maximizing incovenience to you, or minimizing it to them, but fact of the matter is, you have a constitutional right to be tried WHERE the crime was commited, and if YOU commited it, you more or less picked your venue.
If a USA bring a GJ in the wrong venue, it ends up being waste, so from a department eficiency standpoint, he should convene GJ were the case is going to be tried, etc. It's not illegal if he convenes a GJ elsewhere. Knock himself out in Alaska or Hawaii for all the court cares.
