Yes, in the right circumstances. Dismissals happen at several points: a clerk-magistrate declines to issue the complaint, a motion to dismiss is granted for lack of probable cause, a motion to suppress guts the case and prosecutors nolle prosequi, pretrial diversion or a CWOF is completed, or a jury returns not-guilty. Massachusetts prosecutors will not dismiss because a defendant is a "good person," but they will dismiss when evidence cannot survive a motion, a witness will not cooperate, or a constitutional violation taints the case. Our job as your Massachusetts criminal defense lawyer is to find the pressure point that creates a dismissal opportunity and apply it hard.
