I was thinking Fairfax county VA when I wrote that but Berkley fits the bill really well too.
Big enough to have enough "real city" problems to get people who have no real existential problems worried, but not enough to keep the police/security busy with "real crime", small enough these people can think that there's serious accountability preventing mundane abuse/misuse (whereas almost nobody in NYC would think that there's accountability for any misuse that isn't regional news worthy) and rich enough to not have to seriously care about resource allocation toward unnecessary security apparatus.
