First of all, an article on how stricter gun control in Australia led to declining homicides and suicides.
Also, while it is true that gun control won't prevent mass assaults of the kind that recently happen here, it does seem to vastly reduce the casualties. China experienced a mass stabbing on the same day that we had a mass shooting occur in the US. A key difference is that in China, no one died, and there tends to be more wounded than fatalities in events of this type in China.
Unfortunately gun control is one of those issues where the US is deeply irrational. Gun control works, anyone denying this is either uninformed, lying, or exhibiting an extreme version of motivated reasoning. As long as we are weighing real benefits vs. imaginary benefits, like tyranny prevention, personal safety, and crime prevention (none of which firearms possession can be shown to contribute to statistically, though some people do appear to feel an increased feeling of personal security even though statistically their security declines through gun ownership) a mature conversation on this topic is impossible. For us to have an adult conversation on the topic will require that we
admit the effectiveness of gun control measures, and then to decide how to
weigh the public health (suicide prevention), crime prevention, and
general personal safety benefits against the fact that some people have
moral beliefs about the role guns play in our society and gain a feeling
of personal safety from them.
Or to put it another way, gun control is a case where we are letting the moral and emotional concerns of a few prevent measurable, universally agreed upon benefits that would accrue to everyone. Maybe we believe that the concerns of these few should trump measurable benefits to the public at large, but if this is what we are doing we should admit to it, rather than continuing to repeat bullshit about guns which just isn't true.
