Anyone who has a California State and Federal Employees Credit Union debit card is probably a good indicator.

I saw an Illinois State Police Federal Credit Union branch recently and really thought to myself... that might be giving away a little more information than I'd be comfortable with if I were a cop. I mean, anyone going to that credit union is pretty likely to be, you know, a police officer. So if a criminal was trying to track down a police officer they had beef with, where would they look? Seems pretty obvious. Seems pretty dangerous.

Police buildings (stations, offices, etc.) where they work every day would probably be more useful than a bank.

I think they meant that they could use public payroll records to get the names of city officials.

My aunt's boyfriend works for California govt and his home address is on display. You'd be surprised at how incompetent and irresponsible govt can be.
