Rodricks: A data dive on Baltimore homicides shows the need to stop retaliatory violence

After he sent me another pile of data about violent crime — specifically, an analysis of the Baltimore Police Department’s performance in making arrests in homicides — I wondered why Thiru Vignarajah, former candidate for mayor and Baltimore State’s Attorney, keeps doing this. To get on Fox 45 again? To stay viable as a political candidate for some future office? Why go to the trouble of looking at four years of violent crimes and arrests? That’s heavy work for a private citizen.
