"Let's all try to make as much money as we can so that we can afford to buy a house in a nice neighborhood, where everyone can afford to pay enough local taxes to support a nice police department with courteous officers who won't

with you like this. Then, we can believe that incidents like this are largely limited to poor areas where the local citizenry are disrespectful & unappreciative of the underpaid, half-a-step-above-thugs they have in uniform, anyhow."
...if that way of thinking seems familiar, check out the
police department where this all took place. Not exactly in the slums. You might think that an uproar would ensue if this happened in a "nice, respectable area," but let's see what the fallout is (if any) from this report.
[edit: It's a shame that our nation's capital should harbor so much poverty. Driving through Washington D.C. is a bizarre trip across filthy slums in close proximity to glitzy shopping strips.
Mind you, I am not implying that police chiefs (in affluent or dilapidated precincts) have an easy job of monitoring their officers. I would not have expected that Miami police chief to pledge that "any offending officers will be sacked" without having first gotten the full story behind the incident, and I'm sure they receive complaints all the time from citizenry against their officers and vice versa (well, maybe not in Florida, where evidentally they don't provide a channel for complaints from the public) which are a headache to resolve.]
