“Our research found that the proposition had no appreciable impact on crime in the year following its enactment. Specifically, it had no effect on rates of homicide, rape, aggravated assault, robbery or burglary. Larceny and motor-vehicle thefts did seem to have increased moderately after Prop 47 went into effect, but these results were both sensitive to small changes in our modeling and small enough that we cannot rule out spuriousness.“
