Given that the county is larger than Camden, I would expect there to be more white cops. You are right to say that the experiment in Camden is hardly a defunding. It is more like a small city putting the onus and cost of policing onto a wider area.
That’s right; there isn’t a lack of police presence in Camden. Bergen County in the northeast went the opposite way, and eliminated their county police (putting the responsibilities on local departments). There is just no money left for these massive government workforces here; the taxes are chasing companies out, destroying the tax base.
