The issue is not solely about race. The issue is how does the state deal with issues of race? In the Trayvon Martin case, you have a racially-biased white man confronting a black teenager after he was told not to do so, and then being absolved by the police as acting in self-defense in a confrontation that the white man clearly initiated. How does that work? A black teen concerned for his own safety when confronted by an agitated southern white male who outweighs him by at least 50 pounds, is, by definition, the aggressor when acting in his own self-defense? I don't get it.
When the local police in Kansas City chooses not to charge the allegedly black suspects because the police conclude the suspects were acting in self-defense, then Karl will have something to say about Travon Martin.
Until then, Karl is full of shit. You'd think a self-professed "libertarian" would get that, but liberty apparently is not color blind.
