The usual NRA talking point. They want their followers to believe that the CDC - The Center for Disease Control-  is junk science and apparently many do - and this is why we fail. 
The NRA narrative is powerful and polarizing and appealing to low information voters in the USA. According to them, any talk of reducing gun violence becomes an attack on the 2nd Ameendment. We need to change this mindset and start saving lives immediately.
