Along with the usual factors that prosecutors consider before recommending a sentence, such as a defendant’s prior criminal history and the severity of the crime, assistant district attorneys in Philadelphia should now also consider how much each jail sentence would cost the taxpayer, according to a new policy outlined by District Attorney Larry Krasner.

On Thursday, Krasner said the cost of incarceration will be considered by prosecutors when making their sentencing recommendations. According to the District Attorney’s Office, Philadelphia will apparently be the first prosecutors’ office in the United States to institute a cost-efficiency policy in sentencing.
