Greg Ridgeway is a statistician turned criminologist who was Associate Director of the National Institute of Justice from 2013 to 2014. During his tenure he authored what has become something of a cult piece for the pro-gun community, namely, amemo called
Summary of Select Firearm Violence Prevention Strategies, which keeps turning up in various pro-gun commentaries as a basic ‘proof’ that gun-control programs don’t work. The latest broadside to cite Ridgeway’s document in approving fashion is a report by David Kopel published
by the Cato Institute, a right-wing think tank that has been promoting the pro-gun agenda for years.
