Old Contra Costa hand here. Lived in Marin, SF, went to school in Crescent City and lived in CC for about 20 years- now living in VA.
The first thing that leapt to mind was ‘how does a cop afford Alamo?’ Last time I looked- admittedly a while ago- that was really pricey turf, and cops usually don’t make huge buckets of money. A well paid cop usually is still south of $100K- unless he’s a chief or something.
I know counterintelligence people look for folks living well beyond their means- do cops do the same?
At www.sfgate.com/data, scroll down to Salaries, where you can scroll down further to Contra Costa County and enter Tanabe's name, then search. You'll find that in 2009 (the last year for which data is available), a Stephen R. Tanabe made nearly $105,000 in total salary.
Go back and select the ALL choice and search. You'll find that the county has a huge number of folks pulling down six figure paychecks. The good taxpayers of Contra Costa County are victims of grand larceny of a huge scale.
