Effect Of Medical Marijuana Legalization On Crime Rates

Effect Of Medical Marijuana Legalization On Crime Rates And Limitations Of Data: "Given that the current results failed to uncover a crime exacerbating effect attributable to MML, it is important to examine the findings with a critical eye. While we report no positive association between MML and any crime type, this does not prove MML has no effect on crime (or even that it reduces crime). It may be the case that an omitted variable, or set of variables, has confounded the associations and masked the true positive effect of MML on crime.

Definition of 'Clearance' in Crime Statistics

"In the UCR Program, a law enforcement agency reports that an offense is cleared by arrest, or solved for crime reporting purposes, when three specific conditions have been met. The three conditions are that at least one person has been:

"• Charged with the commission of the offense.
"• Turned over to the court for prosecution (whether following arrest, courtsummons, or police notice).
