From a new Trevor Burrus article on which policy ideas might significantly reduce firearms death rates, and which almost certainly won’t:
Allow the CDC to make recommendations for gun reform: First of all, the CDC is not “banned” from studying gun violence. Here is a 110 page CDC study on gun violence from 2013. The CDC is banned from advocating or promoting gun control, which makes sense because such advocacy is not science. Advocacy from the CDC is problematic, such as when it advocates state-controlled liquor sales, and the imprimatur of the CDC can confuse as well as illuminate.
