This is one of the most glaring racial biases in US law, and SCOTUS
has only just begun to attempt to correct it. The whole article
points up a lot of remaining disparities, including the differential
easing of laws that govern drugs more often used by white people. And
if you're prone to thinking we shouldn't give a damn about the
disposition of drug dealers, tell me who you'd do if caffeine was
suddenly illegal and out of your income range as a result.
