But there's one public health concern that hasn't received funding in nearly two decades: firearm regulations. Firearms accounted for more than 30,000 deaths in 2014 — about the same number as died from motor vehicle accidents. With vanishingly few studies to investigate firearm deaths, however, researchers are unable to recommend the best course of action for public health officials to take. In 1996, Congress passed legislation that specifically prohibited the use of government funds for the promotion of of gun control. Fearing funding cuts, the government agencies that hand out grants to researchers instated a self-imposed ban on any sort of research into firearms. The CDC has funded no studies directly related to firearms, while the NIH has been only slightly less cautious — despite a 2013 memorandum from President Barack Obama instructing both agencies to begin funding research into gun violence. More often than not, researchers rely on their own resources to conduct their work.
