For every black and every white unwilling to condemn the protests over Michael Brown’s killing that took place before any relevant facts came out, their half-hearted condemnation of the riots notwithstanding, truth doesn’t matter. The protests, riots, and liberal condemnations of the white officer began when no one knew anything about the killing.

There is, then, some validity to this notion of blacks and whites’ having different perceptions. But when the truth is knowable, one of the “perceptions” has to be wrong. Two distinct ethnic or cultural groups may have different perceptions of musical beauty or of what foods they like. But this is not the case regarding truth, which is based on facts. In Ferguson, either the black (and left-wing whites’) “perception” is not truth-based or the other side’s “perception” isn’t.

Once the facts come out, we are no longer speaking of “perceptions.” We are speaking of truth and falsehood.
