Law enforcement officers have often described [marijuana] arrests as a way of reining in criminals whose other, more serious activities present a danger to the public. But state statistics show that of the nearly 12,000 teenagers arrested last year, nearly 94 percent had no prior convictions and nearly half had never been arrested.

Now a new study by Human Rights Watch further debunks the main premise of New York City’s “broken windows” law enforcement campaign, which holds that clamping down on small offenses like simple marijuana possession prevents serious crime and gets hard-core criminals off the streets.

The study tracked about 30,000 people arrested for marijuana possession in 2003-4 — none of whom had prior convictions — for periods of six-and-a-half to eight-and-a-half years. The study found that about only 1,000 of them had a subsequent violent felony conviction. Some had misdemeanor or felony drug convictions, but more than 90 percent of the study group had no felony convictions whatsoever. The report concluded that the Police Department was sweeping “large numbers of people into New York City’s criminal justice system — particularly young people of color — who do not subsequently engage in violent crime.” This wastes millions of dollars and unfairly puts people through the criminal system.
