Just to be absolutely picky here - this man was not 4.5 times over the "legal limit" we think of, that is .08 for driving. In fact he was .089 which is over four times the legal limit for pilots, or just barely over the legal limit for drivers in most countries. That said, he indeed should have been removed and jailed for his actions. If you Google him you'll find he's a strange character.
