You do realize that public health researchers are not the experts in crime, right? That they have their own expertise and should focus thei resources on that expertise, like stopping the hundreds of thousands of deaths due to medical errors or actually fighting diseases like Zika and drug-resistant tuberculosis.

In any event, solid research is still done by economists and criminologists, the actual subject matter experts, DOJ, state and local as well as by private and public universities. And the CDC still collects the data, the ban is on them producing poorly constructed propaganda in the guise of research.

Hell, the CDC just did some solid work in Baltimore that reinforces how violence is a problem of small, violent sub-cultures of loose associates. Which reinforces Papachristos work in Chicago and the King County ER study. People problem, not gun problem.
