"An individual who has an out-of-control addiction commits about 63 crimes a year. Assuming this could be reduced to 10 for someone who is in or has completed treatment, and multiplying it by the 200 offenders in Delaware's probation revocation track who comply with all requirements, a single drug court may prevent more than 10,000 crimes each year."
