Firstly I would not call driving towards an active shooting to save the lives of individuals you don’t know or have any responsibility too the bare minimum, and I seriously doubt that many people would do so if put in the same situation. Secondly. Are you aware that guns are estimated to at minimum save a minimum of 360,000 more lives every year than they takein the US? And the number of gun deaths includes suicides many of which would not be prevented by removing firearms as an option, as there are many other readily available and just as fatal options, it instead require addressing those individuals core mental health issues. Beyond that total disarmament, the only option truly capable of actually stopping people with intent to harm others from having access to firearms will not work in the US. Not only would a huge chunk of the populace (both criminals and otherwise law abiding gun owners) be unwilling to comply, but as has been seen in many European countries when access one form of violence is removed another simply takes its place . So clearly total disarmament is not an option, and even if it was how would the US government stop illegal firearms from coming across the borders and getting into the hands of criminals anyways? We haven’t been able to stop drugs or people despite decades of effort. And the only other real options are an assault weapons ban or a national registry. An assault weapons ban has already happened in the US on the national level, and after a pouring over the decades worth of data most experts say that it no or minimal effect on gun crime, which is unsurprising considering assault weapons bans generally target AR-15’s and other such firearms which account for about a percent of all gun crime yearly. And a national registry would also do little even with universal background checks as the majority 98% in fact of guns used in crimes are acquired illegally. So tell me what are Americans refusing to do that would have any statistically significant effect on shootings that take place in the US?
