Fighting the Crack/Coke Disparity

Congress is considering a bill that would close the crack/cocaine disparity (for some good links talking about the disparity read this Racewire article) by reducing penalties for crack cocaine. If passed the bill, dubbed the Fair Sentencing Act, will increase the amount of crack (to 500 grams) that would get you 5 years in prison to the same amount as is required now for selling powder cocaine. Obama has said in the past that he is committed to equalizing prison sentences for crack and coke but has been silent thus far on the Fair Sentencing Act.

It is worth noting that many conservatives want the punishment for cocaine to be increased rather than see a reduction in crack sentencing, but that lawmakers are citing economic reasons for avoiding that route - prisons are now being seen as an economic liability even if they are still considered necessary.

Along those lines -- I'm all about reducing or eliminating the disparity but in the Washington Post article about the bill they also mention that it would "stiffen penalties for large-scale drug traffickers and violent criminals." I'm just curious how this expansion of the prison system managed to finagle its way into the bill. Do the lawmakers who are purportedly about reducing or eliminating racist laws not understand the implications of ANY expansion of the PIC? Do they think that these "stiffened penalties" are going to equally affect all people? I'm just baffled at the lack of basic sense... who are we fighting here? Who are we protecting?
