Did the National Research Council Report on “Firearms and Violence: A Critical Review” show that right-to-carry laws don’t reduce crime?

A frequent claim by gun control advocates is that the National Research Council (NRC) 2005 report, “Firearms and Violence: A Critical Review,” has “debunked,” “emphatically rejected,” “disproved,” or failed to support research showing that right-to-carry laws reduce crime.  It is not too surprising that gun control advocates and the media like to point to their interpretation of the NRC report because the studies that look at the data for the US normally find strong support for right-to-carry laws reducing violent crime.  …

Responding to John Donohue’s responses to our evaluation of his new study

John Donohue responded to our comments on our website and in an op-ed at Fox News.  Below we go through and respond to the points that he raised.  Amusingly, the author of the original piece in Michael Bloomberg’s “The Trace” emailed Donohue as soon as my comments came out.  While The Trace pretends to be a regular news outlet, Mr.…

The flawed and misleading Donohue, Aneja, & Weber Study claiming right-to-carry laws increase violent crime

A new, unpublished study by John Donohue, Abhay Aneja, and Kyle Weber has received a lot of attention for supposedly finding some evidence that right-to-carry laws increase overall violent crime rates.  It has been covered in Newsweek, The Atlantic, Bloomberg, Vice, Snopes, and many newspapers such as Newsday and the Salt Lake City Tribune.  …

Evaluating Bloomberg’s School of Public Health’s “Firearms on College Campuses”

This paper by the Bloomberg School of Public Health (copy available here, henceforth referred to as the Bloomberg Report) doesn’t even try to address the existing arguments that have been made on campus carry.  Below is a very rough, very quick response to their claims.  For those who are interested, here is a video of recently invited testimony that Dr.…

A response to Mother Jones’ mistake filled article on John Lott and the Crime Prevention Research Center

The altered image above is from a new Mother Jones’ article, which was written to try discrediting John Lott and the Crime Prevention Research Center.

Mother Jones is willing to do anything to push for gun control.  The magazine is very left-leaning and is funded by individuals such as George Soros. …

CPRC in the Washington Post: “‘New’ research on gun laws and crime was flawed”

The CPRC has a letter to the editor today at the Washington Post that discusses a recent working paper that was discussed in the Post on November 14th.

Dear Letters Editor:

Christopher Ingraham’s “More Guns, More Crime” ignored research critical of a slightly updated, error-ridden paper by law professor John Donohue and two graduate students co-authors.

Problems with the Washington Post’s and Huffington Post’s “more guns, more crime” claims

The media over the last couple of days has been pointing to a revised paper by Abhay Aneja, John J. Donohue III, and Alexandria Zhang that has been floating around in various forms since at least 2009.  Their earlier paper claimed that right-to-carry laws and no impact on murder, rape and robber. …

What does the research on the death penalty actually show?

The 2012 National Research Council report on “Deterrence and the Death Penalty” has a table showing only 10 panel studies on the death penalty (those shown above in plain type). No explanation is provided for why these studies are excluded. I have placed one of my studies showing some weak support for the death penalty in the “no clear effect” column, but it presumably would have been difficult for them to include that and ignore my other research showing a clear and consistent benefit from these laws.…
