As for the "not much funding" and "not much research," that's absolute nonsense and points up the big problem with public health researchers pontificating about firearms safety and gun crime. They simply are not qualified to discuss either topic and repeatedly show their ignorance (born of either arrogance or incompetence) of the extant 40 plus years of solid research by the -actual- subject matter experts, criminologists and economists, in both public and private sectors, at local, state, and national levels. 

Aside from their absolutely unscientific starting premise that "legal gun ownership -is- a public health problem" (the false assumption that resulted in the bad research to prove that premise which got the CDC funding limited); their unwillingness to learn from the experts who have been doing research for decades and who constantly have to point out where the PH research goes wrong due to methodological failures or lack of knowledge of the topic gets very tiring to deal with.
