Go here to see that the NYC "Aggressive Arrest Policy" Sabet lauds actually focused overwhelmingly on the misdemeanor "smoking marijuana in public view", (MPV): http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2561263/figure/F1/
Observe that while the number of people busted for smoking on the street skyrocketed, arrests for other cannabis-related offences remained relatively stable. Arrests for non-drug misdemeanors also increased.
However arrests for other drug offences ("controlled substances") and for non-drug felony offences (both of which should be of greater concern to the community than smoking cannabis or non-drug misdemeanors) fell dramatically.
Go here to see that all these extra MPV charges overwhelmingly targeted Hispanic and Afro-American people;
<<< Since 1980, the New York City Police Department (NYPD) expanded its use of arrest and detention for minor offenses under its quality-of-life (QOL) policing initiative. Arrest data indicate that during the 1990s the primary focus of QOL policing became smoking marijuana in public view (MPV). By 2000, MPV had become the most common misdemeanor arrest, accounting for 15% of all NYC adult arrests and rivaling controlled substance arrests as the primary focus of drug abuse control. Of note, most MPV arrestees have been black or Hispanic. Furthermore, black and Hispanic MPV arrestees have been more likely to be detained prior to arraignment, convicted, and sentenced to jail than their white counterparts. >>>
This policy appears to prioritise forcing people who don't need or request it into drug treatment, (along the way disproportionately incarcerating or criminalizing Black and Hispanic New Yorkers), and simultaneously policing more serious and antisocial crime in a significantly less effective fashion.
