Whenever an unarmed black person gets shot to death, the way Trayvon Martin was, you'll hear some people defend the shooter by claiming that the shooting wasn't racist, and how dare you judge what's in the shooter's heart? The shooter would have killed any unarmed person for walking down the street in a sweatshirt, or walking down the street with a wallet, or performing whatever "suspicious" everyday activity prompted the homicide. The defense is that the killer is not a racist, but a universal menace to society. This is supposed to be reassuring somehow. It's a thoroughly illogical defense. It even suggests that no matter what the person making the argument says, and no matter what they tell themselves, they know in their hearts that racism was the motive for the violence. In fact, their own sense of safety is based on their rock-bottom belief that the killing was racist.
