I don't know if COPS is the show I've seen, but there's one where the cops are followed around busting down doors and generally terrorizing a bunch of down-and-out members of the underclass in their own wretched little hovels for heinous crimes such as trying to escape from their miserable surroundings with a little dope, the poor man's travel alternative. I always thought it should be re-titled "Stormtroopers in Amerika," and wondered how many Americans were getting their vicarious jollies from such a frank and unsavoury close-up of the rich and the powerful bullying the weak and the seriously fucked up. I don't remember anything about the announcer, though. Not even if it's a man or a woman.
=================================
That is COPS. It is shown here on FOX, but it might be a syndicated show. While the cops are pursuing their inept quarry, they play this song, that asks the musical question, "Bad boys, bad boys, where you gonna go when they come for you?"
The cops are not depicted as rich, they are almost as inarticulate and ungrammatical as their prey. The criminals are poorly groomed and ill-clad, and are only barely able to speak. They offer only the lamest of excuses for their weird behavior. Usually, there is a chase, and after they are captured, they explain that they knew there was a warrant out for their address and did not wish to return to jail.
The cops are generally overweight and seem to have been stuffed into their uniforms several sizes too small. They resemble sausages, and are decorated with all manner of weaponry and devices, reminiscent of Batman's utility belt.
The announcer is a guy with a somewhat whiney voice who makes dumbass comments, such as "There's one reckless driver that won't be endangering others anytime soon".
These comments are after the fashion of Lt. Joe Friday or Dragnet, or more recently, David Caruso's character of CSI: Miami, but sound even more sleazy.
