Abstract
This paper empirically documents one way in which prosecutorial discretion can be used to dampen the effects of mandatory minimum sentencing laws. Specifically, I show prosecutors use their discretion over prosecution charges to circumvent a mandatory minimum sentencing law for some defendants, by prosecuting these de- fendants who were initially arrested for the crime targeted by the sentencing law for lesser crimes not covered by the law. I document the use of such discretion with respect to several state "three-strikes" type repeat offender laws imposed through- out the 1990s, where I find that prosecutors become significantly more likely to lower a defendant's prosecution charge to a misdemeanor when conviction for the initial felony arrest charge would likely lead to sentencing under a three-strikes law. Moreover, accounting for such behavior is important, as I show that failure to do so can lead to overstating the effects of these laws on average sentencing by almost thirty percent.
