Dan Rodricks: Will Marilyn Mosby’s shift in prosecution priorities make a dent in Baltimore’s murder rate?

As of Thursday morning, there had been 2,259 homicides in Baltimore during the nearly seven years Marilyn Mosby has been the city’s top prosecutor; that’s an average of around 322 murders a year since 2015. During the four years previous, when Gregg Bernstein was Baltimore state’s attorney, the city averaged 215 homicides a year. I make the comparison only because, as she campaigned to unseat Bernstein in the 2014 Democratic primary, Mosby criticized him as ineffective and blamed him for the relatively modest increase in city violence, from 197 homicides in 2011 to 211 in 2014.
