I think at the very least there should be some kind of juror training process. You'd still tap people from the general public, but these people could maybe serve up to 5 year terms where being a juror is their full time job for that time period, they're trained in advance, they go through some kind of testing period, maybe shadow a couple other juries, and then they go on to serve on real juries. Obviously this would be a paid position much like a postal employee.
