Dorner is a shithead, but he’s not waging a ‘race war’. If he simply wanted to kill white people, he’d have done more killing than he already has done. It’s pretty clear that his target is the LAPD, as he says it is.
That said, I knew the race card would be played by Rush and his ilk. Christopher Dorner is the latest “Scary Black Man” trotted out by Limbaugh to rile up his listeners. Unlike some others, he’s actually scary (though not because he’s black, because he’s a murderer).
