After more than two decades, a glaring, and unfair, disparity in the nation's sentencing laws is on its way to being corrected.

The House of Representatives this past week joined the Senate in changing a mid-1980s law that imposed much harsher sentences for crack cocaine than for powdered cocaine. Put simply, the disparity disproportionately affected blacks. That's because crack is a cheaper form of cocaine more prevalently used by African-Americans in low-income, inner-city neighborhoods.
