2. I think STUPIDITY is the leader in the explanation game, there.
Why would a couple of four stars think that their pompous word would sway a judge in a legal matter?
Answer: They are idiots who have lived too long in a fawning bubble where people are overly impressed by their rank. I get a kick out of people who don't know a corporal from a general--and I enjoy the discomfiture of flag/general officers who have trouble dealing with those sorts. Everyone started out at the beginning when they joined the service--on the ground floor, either enlisted or officer (and sometimes, both for the odd mustang or person who applies for a commission).
It's the really dumb ones who don't remember where they came from.
It didn't work out too well for their letter-writing efforts, in any event. Not only did sis lose, she was ordered to pay a fortune to the ex.
