Considering the unprecedented murder surge in America's cities over the last two years, one might expect progressive district attorneys to reconsider the policies that have kept criminals out of jails and on the streets. Think again. Last week, Philadelphia district attorney Larry Krasner told a local television news anchor he's not prepared to change course. 'It is working,' Krasner claimed, a few days after another mass shooting had killed a 14-year-old football player and wounded four of his teammates following a high school scrimmage. The anchor noted incredulously that a thousand people had been killed in Philadelphia over 20 months. 'It is working,' insisted Krasner. Krasner apparently defines a policy as 'working' when it contributes to the highest number of murders and the highest murder rate in a city's history, a record number of carjackings, the routine looting of stores, and savage beatings of innocent pedestrians. Krasner has a knack for denying the undeniable.
