From the New York State Office of the Attorney General Report:
In this report, stop-and-frisk data confirm that racial disparities documented in stops continue through arrest, disposition, and sentencing. This disparity is especially pronounced in marijuana arrests, in which white defendants charged with misdemeanor marijuana possession after a stop are nearly 50% more likely than blacks to receive an ACD, and thereby avoid a conviction.
ACD [adjournment in contemplation of dimissal) also known in some locales as an ACoD is a mechanism which allows for the postponement of a criminal case with the understanding that if the accused fulfills certain conditions, all charges will be dismissed.
