Effect of Mandatory Minimum Sentencing Laws on Crime and Arrest Rates
"Though it is still too early to make a final judgment, RAND found that three strikes and truth-in-sentencing laws have had little significant impact on crime and arrest rates. According to the Uniform Crime Reports, states with neither a three strikes nor a truth-in-sentencing law had the lowest rates of index crimes, whereas index crime rates were highest in states with both types of get-tough laws."
