Average Police Time Taken Per Marijuana Arrest: "In those eleven years the NYPD made a total of 439,056 possession-only arrests. Multiplied by two and a half hours of police time per arrest that equals 1,097,640 hours - or approximately one million hours of police officer time to make 440,000 marijuana arrests. That is the equivalent of having 31 police officers working eight hours a day, 365 days a year, for 11 years, making only marijuana possession arrests."
"Police departments deploy most patrol and narcotics police to certain neighborhoods, usually designated "high crime." These are disproportionately low-income, and disproportionately African-American and Latino neighborhoods. It is in these neighborhoods where the police make most patrols, and where they stop and search the most vehicles and individuals, looking for "contraband" of any type in order to make an arrest. The item that young people in any neighborhood are most likely to possess, which can get them arrested, is a small amount of marijuana.
