This is not about the general issue of gun control. I don't have strong views about gun control, at least if we're talking about rifles and handguns, as opposed to mortars or rocket-propelled grenades. I am not saying this as the opening salvo in a ban to criminalize the private possession of firearms. This is not the entering edge of any wedge, or the first step down a slippery slope. I just think that there should be some process, with safeguards and due process to guard against abuse, that makes it possible to prevent someone who from getting a gun when there is clear evidence that that person is homicidal.
