I live a couple miles South of El Segundo and worked there for years. My Dad worked in the city for 40 years and my Wife graduated from El Segundo High.
For as long as I can remember, local cops and firemen had looked at getting a job there as winning the lottery. The city used to be awash in cash, partly because it was a major aerospace manufacturing hub (nearly all union labor that made sure city officials were union-friendly). Much of that money has dried up now. The Chevron refinery also contributes heavily to the city's tax coffers.
Many of the big wheels in the city are Mormons. Cops are prohibited from using tobacco either on or off duty. It's well known locally that you simply do not speed or break any other traffic rules in El Segundo unless you want a ticket. Cops don't have much else to do.
Last I heard, El Segundo Fire Dept. was broke and about to let LA County Fire Dept. take over...
