Barack Obama's understanding of what the drug war had cost the country was meaningful. And very quietly in his second term, he and Eric Holder did make some adjustments in terms of the use of the Department of Justice, on the federal level.

You also saw, on the part of some certain states, a realization that they followed the war on drugs to a useless place, that they were only doing damage to communities, and bankrupting budgets with prison construction.
