Would it surprise you to learn that government agencies are banned from gun research?
In 1996, Congress barred research by the CDC that might "advocate or promote gun control." In 2003, the Bureau of Alcohol, Tobacco, Firearms and Explosives was banned from providing researchers with data on gun injuries and deaths. And in 2012, the National Institutes of Health was barred from funding gun research.
Obama could overturn those bans via executive order, a step the Atlantic Wire calls the "order the NRA should fear the most." The NRA favors restrictions on gun research, and lobbied for the part of Obamacare that bars doctors from providing data on gun injuries to researchers.
Currently there is no scientific consensus on relationship between gun ownership and gun deaths. There simply aren't enough studies to know whether higher gun ownership would prevent gun deaths, or increase them. With more studies, the government might learn which gun control policies - if any - would prevent gun violence and gun-related deaths.
Overturning the CDC's gun research ban is among 19 orders that Obama is considering as part of the gun control package cooked up by Joe Biden.
