The truth about gun free zones
by Dr. John R. Lott
Gun control advocates this month took a page from the global warming activists playbook: the science is settled, so there is no need for debate.
However, instead of actually reviewing the scientific literature on the subject, Professor David Hemenway at Harvard made a survey of cherry-picked authors. Surprisingly, he found the vast majority agreed that we need more gun control.
So let’s look at the details. He polled authors who had published in the fields of “public health, public policy, sociology, or criminology.” Most notably, half of the authors picked were within Hemenway’s own field of public health and another third were sociologists/criminologists, followed by public policy and a few economists. It dramatically over weighted those in public health. It didn’t matter whether the publications even contained any empirical work or were related to the survey questions.
