Cops? Or Soldiers?

Posse Comitatus FORBIDS the use of soldiers as policemen. But what about the use of cops AS SOLDIERS? In this case, this is what happened: “From the way police entered the house—helmeted and masked, guns drawn and shields in front, knocking down the door with a battering ram and rushing inside—you might think they were raiding a den of armed criminals. In fact they were looking for $1,000-worth of clothes and electronics allegedly bought with a stolen credit card. They found none of these things, but arrested two people in the house on 'unrelated' charges” (Charges designed to legitimize the raid). The homeowner’s son, a legally-armed ex soldier, put his gun away when he heard them say they were cops and thus was not shot to death by this “invading army” of blue-clad soldiers. Of course, even though they found nothing, they still came up with some phony ‘charges” to justify this “hob-nailed boots raid” on innocent people. This happened in Ankeny, Iowa; not a region of massive crime, but this tiny police force still had this SWAT Team to use on a “CREDIT CARD VIOLATION.” What's next? A SWAT raid to break up a bar fight? (The Economist)
