@ray That's not what the data said at all.....
"In Brooklyn, officers in the precinct covering Canarsie arrested people on marijuana possession charges at a rate more than four times as high as in the precinct that includes Greenpoint, despite residents calling 311, the city’s help line, and 911 to complain about marijuana at the same rate, police data show. The Canarsie precinct is 85 percent black. The Greenpoint precinct is 4 percent black.
In Queens, the marijuana arrest rate is more than 10 times as high in the precinct covering Queens Village as it is in precinct that serves Forest Hills. Both got marijuana complaints at the same rate, but the Queens Village precinct is just over half black, while the one covering Forest Hills has a tiny portion of black residents.
And in Manhattan, officers in a precinct covering a stretch of western Harlem make marijuana arrests at double the rate of their counterparts in a precinct covering the northern part of the Upper West Side. Both received complaints at the same rate, but the precinct covering western Harlem has double the percentage of black residents as the one that serves the Upper West Side."
