SCIENCE: DOJ Researchers Conclude Assault Weapons Ban Won’t Cut Gun Violence. The science is settled. You can’t argue with science. You don’t want to be a science-denier, do you? Well, I guess some people do:

Justice Department researchers have concluded that an assault weapons ban is “unlikely to have an effect on gun violence,” but President Obama has not accepted their report as his administration’s official position.

“Since assault weapons are not a major contributor to US gun homicide and the existing stock of guns is large, an assault weapon ban is unlikely to have an impact on gun violence,” the DOJ’s National Institute for Justice explains in a January 4 report obtained by the National Rifle Association. “If coupled with a gun buyback and no exemptions then it could be effective.” That idea is also undermined by the acknowledgement that “a complete elimination of assault weapons would not have a large impact on gun homicides.”

The research in that report didn’t stop Obama denouncing “weapons of war” during his State of the Union speech on February 12.
