Study: Marijuana legalization doesnt increase crime
According to data from the Denver Police Department, violent crime (including homicide, sexual assault, robbery, and aggravated assault) fell by 6.9% in the first quarter of 2014, compared with the same period in 2013. Property crime (including burglary, larceny, auto theft, theft from motor vehicle and arson) dropped by 11.1%.
