With minimum mandatory sentences and DAs who are looking to up their conviction rates, the DA adds "with intent to distribute" to the charges against the black man.  After all, if he wasn't guilty, why would he run? Now faced with serious charges and extensive jail time, the DA offers a plea deal which will result in a drastically reduced sentence.  What a guy.
The black man takes the plea because he can't afford a high-profile lawyer who either knows the judge or the DA and he knows that a black man would never be given the benefit of the doubt in a trial.  After all, blacks commit a disproportionate number of crimes...
Now he is just one more statistic proving that to be "true."
