'This crack cocaine thing' refers to the long-standing unequal conviction and sentencing laws for powdered vs. crack cocaine- an obvious racial imbalance. Whites prefer powdered cocaine which carries more lenient sentencing guidelines than the black-preferred crack.
We're gonna get it done. Seems it takes a while for GOP congressmen to 'get it' as they prefer to roll around in the muck quite a while before moving towards equality under the law. I suppose it 'teaches' them coloreds that freedom really isn't free unless your skin is lacks melanin. Keeps them from getting too uppity, you know. If you let them have an inch, you know that pretty soon, they'll want to move into your neighborhood!
Best not act too fast. You all know what I'm gett'n at, don't ya?
