I’ve said it before, solving crimes - particularly violence - is arguably the most important task of policing. If used right (rapidly, consistently, and with due process), technology is the game changer. 1/3 Unfortunately, the trend line is moving in the wrong direction. @Crimealytics in The NY Times has a prescription that makes sense: enough officers to respond, make more officers detectives, more civilianization, dedicate more analytic resources. 2/3

A few thoughts about the recurring crisis in policing. I’ve been speaking publicly about police misconduct since Jonathan Ferrell was killed in 2013 by a Charlotte officer.
