rdtsc isn't defending the actions of bad cops by pointing out that the vast majority of cops are good cops, he's saying that in a police state, the majority of cops will be corrupt arseholes, which isn't the case here in the USA. Thus, all of the claims that the USA is a police state is a police state are superficial, and I agree. We are certainly headed in that direction, but we are not there yet, not even close, really.
A country that portrays itself as a beacon of light in a dark world ought to judge itself by both its direction and the extreme cases, not by its relative position and the median cases.
