I’m not exactly sure by what Rube Goldbergian chain of events Bratton thinks legalization in Colorado and Washington is causing homicides in New York City, but it’s clear that he thinks there’s a connection. Another NYPD official said the problem appears to be “ripoffs” — not turf battles, but attempted robberies gone wrong.
Of course, if we want a more direct examination of what effect legal pot might have on homicide, we can just look at the cities where it’s legal. Here’s what we know:
Homicides dropped 24 percent in Denver last year, the first full year of legalization in Colorado. Robberies were down 3 percent. Burglary was down 9.5 percent. The only crimes that increased significantly were larceny (a property crime, not a violent crime) and arson, which seems unlikely to be related to marijuana. Overall, violent crime dropped 0.7 percent, and property crime dropped 2 percent.
Of course, we only have a year’s worth of data from Colorado. But then, Bratton is drawing broad conclusions based on just eight weeks.
I won’t argue that legalized marijuana is responsible for the 24 percent drop in homicides in Denver last year. There’s not nearly enough data to jump to a conclusion like that. But it’s still a hell of a lot more defensible than arguing that it’s responsible for an increase in homicides in New York.
