Jason Riley writing in the Wall Street Journal reports:
Last September the Obama administration produced an FBI report that said mass shooting attacks and deaths were up sharply—by an average annual rate of about 16% between 2000 and 2013. Moreover, the problem was worsening. “The findings establish an increasing frequency of incidents,” said the authors. “During the first 7 years included in the study, an average of 6.4 incidents occurred annually. In the last 7 years of the study, that average increased to 16.4 incidents annually.”
….But late last week, J. Pete Blair and M. Hunter Martaindale, two academics at Texas State University who co-authored the FBI report, acknowledged that “our data is imperfect.” They said that the news media “got it wrong” last year when they “mistakenly reported mass shootings were on the rise.”
….John Lott of the Crime Prevention Research Center—who has studied FBI crime data for three decades—told me in an interview that the FBI report is better understood as a political document than as a work of serious social science. For example, the authors chose the year 2000 as their starting point “even though anyone who has studied these trends knows that 2000 and 2001 were unusually quiet and had few mass shootings.” Data going back to the mid-1970s is readily available but was ignored. How come? Over the past 40 years, there has been no statistically significant increase in mass shootings in the U.S.
