We don't need Lt's on daywork to manage people working at night. They should be permanently put on the graveyard shift like the people they're in charge of. At the very least, they should be working their area's peak hours. The same goes for the detectives. Except for white collar, all the detective units should have people permanently working peak hours overnight. Major Crimes is structured and managed like a small county sheriffs office in the country with low crime, with everyone on pagers instead
