to 8chan. that's the online message board. what can federalhori do about this spread of what's being called white nationalist messages? >> norah, this is the fourth time a white nationalist terrorist has posted. poway, pittsburgh and christchurch, all those shooters also posted there. look, normally this would be a violation of a terms of service and you'd expect the social media provider to take it down themselves. 8chan doesn't monitor and so, frankly, if i was a federal prosecutor right now, i'd be looking at federal charges for material support to terrorism against 8chan. they are on notice. they know they're being used in this way and they seem to be doing nothing to stop it. the other route is to go ask the american internet service providers to not host this site any longer. i'd be pursuing both routes. >> that conversation is going to continue. thank you, fran townsend.

nevada, underscoring the patchwork nature of u.s. gun laws. california has placed restrictions on these types of rifles, manufacturers simply modify the design of new models to keep them legal and satisfy their customers. older models can still be purchased second hand. >> if anybody wants to buy one, they can go pretty much any flee market that sells guns or any gun show and buy something in the parking lot if they are so inclined. >> reporter: the u.s. banned the manufacture of assault-style weapons for ten years ending in 2004. earlier this year, the bill's author, senator dianne feinstein, proposed a similar ban that stalled in the senate. some estimates put the number of assault-style rifles currently in circulation in the u.s. at 15 to 20 million. the los angeles county sheriff tweeted his call for an end to the manufacture and sale of many of them. >> kris van cleave, thank you. and there's still much more ahead right here. what a group of doctors is doing to stop gun violence. and later, the new mural in el

its forms. rainey is the chief research officer for affirm, an organization trying to address gun violence through the same tools doctors use to combat problems like obesity, the opioid crisis and heart disease. >> that $2.5 million fund that we're raising is going to be to help us identify the shooters before they shoot. >> reporter: but back in 1996, congress cut cdc funding for research on how to prevent gun death because of fears it would promote gun control. dr. garon's work on gun violence lost funding. >> and the rushltesult, i belies that tens of thousands of people are dead today whose lives could have been saved if that research had been done. >> reporter: semiautomatic rifles deliver high velocity bullets that can explode and fragment once inside the body causing devastating injuries. so, norah, wounded victims able to be saved at surgery may face years, even a lifetime of pain and disability. >> important to hear from those.

years of effort to understand and prevent a huge health problem. >> reporter: dr. garon's work on handgun violence lost government funding after congress passed that 1996 legislation. >> consciously, deliberately, repeatedly, over and over, we turned our back on this problem. it's as if we as a country had said, let's not study motor vehicle injuries. let's not study heart disease or cancer or hiv/aids. and the result, i believe, is that tens of thnousands of peope are dead today whose lives could have been saved if that research had been done. >> reporter: in 2018, congress said government dollars could be used to research gun violence, just not to promote gun control. but wintamute says federal research is still underfunded. while private donations for research are now increasing, over the years, dr. wintamute has spent more than $2 million

of his own money to continue his research at the university of california, davis. >> are you a wealthy man who can afford to just do that as a rounding error? >> it's not rounding error, but i live a very simple life and i earn an academic sector e.r. doc's salary. >> so you're changing your salary in order to fund this research, or have in the past? >> yes, that's correct. >> what drives you to do that? >> people are dying. given the capacity to do it, how can i not? it really is just that simple. >> his work has led to some surprising conclusions. for example, his studies reveal that in some states, comprehensive background checks as implemented had no effect on the number of firearm related deaths. that's in part because of a lack of communication among agencies. >> we have learned that probably hundreds of thousands of prohibiting events every year do

not become part of the data that the background checks are run on. >> reporter: consider the 2017 shooting of 47 parishioners at a church in sutherland springs, texas. >> we've lost some great friends today. >> reporter: due to a domestic violence conviction, the shooter should have been stopped from buying any guns. but that information was never shared with the fbi which oversees the background check system. >> so you think, okay, it's not as effective as we want, but it can become effective if we do a, b and c? >> no question about it. >> reporter: but its policy proposals from doctors on issues like background checks and registrations that concern gun rights advocates. >> the point the nra was trying to make with its tweet was, what makes doctors experts on gun policy? >> doctors are not experts on gun policy unless they do their homework. what doctors are experts on is the consequences of violence. if doctors can become experts on policy.

>> is advocating for gun control part of your mission? >> no. this is about stopping shooters before they shoot. >> reporter: the nra did not respond to our repeated request for an on-camera interview. however, in a phone conversation earlier this year, two representatives said the organization does support research into gun-related violence but expressed concern that, say what they will, the ultimate goal of many who advocate such research is to take away the guns of responsible citizens. >> we're not well served by this overly simp pliftic view of simply two sides fighting each other. we have to work together. and that includes engaging firearm owners as part of the solution. >> reporter: for these doctors, the issue is not about whose lane it is. it's about what they can do. >> i know that the house of medicine can fix this. >> yes. >> and enough is enough.
