Economics behind the Dorner case

It's only been a few days, but If the cops are protecting 50 families 24/7, and if it takes 5.5 officers to protect each family, you're looking at 275 officers, and that doesn't count all the investigators working with other law enforcement agencies in trying to track down the guy. Not that Dorner is about to break the LAPD bank, but the case is getting expensive, and it comes at a time when the LAPD already owes its officers 2.3 million hours of overtime, with a total cash value of $85 million (here's the latest budget report by Chief Administrative Officer Miguel Santana). The department has been giving cops time-off rather than cash to cover overtime hours - a practice that has left a typical shift several hundred officers short.
