Ok, I have some more time to post now. I think the first thing we have to decide is what problems are we trying to solve. Gun violence in general? Or just these mass shootings. If we are just trying to limit damage in mass shootings, then I think reducing magazine capacity is one way of doing that. It is going to slow someone down a little bit changing magazines every ten rounds vs. every thirty or fifty or more. Definitely need to outlaw high capacity drum magazines. I don't see any value in banning what are known as "assault weapons." A person can do more damage at close range with a .40 cal Glock with multiple 17 round magazines than he could do with a .223 cal. "assault rifle", in my opinion.
But if we really want to have an effect on firearms deaths in general, including these mass killings, I think we have to take several actions. The first is to provide a more lenient standard for civil commitment of the mentally ill so it is easier to force people into treatment, and also provide money for keeping them in treatment longer than we currently do when they are committed. (I have prosecuted over fifty civil commitment hearings in my life, so can speak directly to this subject with knowledge of how the system works. Simply put -- it doesn't.) Probably also need "parole" type conditions on them when they get out, such that they have to meet with a mental health officer regularly for evaluation and testing to ensure they are taking their meds. Every mass shooting that I have ever heard of was committed by a crazy person. The one here in my home town was committed by a University Professor that was known by coworkers to be crazy (which is probably why she was denied tenure, which is what set her off) and she killed multiple people with a pistol. It isn't always assault weapons, but it is always a crazy person. So rather than ban assault weapons, let's first deal with the crazy population in a realistic manner.
Second, it is a tired cliche that guns don't kill people, people do. But it is a cliche because there is a certain amount of truth to it. And in my mind, the first person that should be held responsible is the gun owner him(or her)self. That's right. I am proposing strict liability for gun owners. We need to have laws requiring guns be kept locked up when not in use. We need laws requiring gun owners to immediately report theft of their firearms (with serious criminal penalties if they don't do so within a reasonable time). And we need a strict liability accessory law. Meaning that if your gun is used by someone else in the commission of a crime, then you are charged as an accessory to the crime. That's right. If your gun gets stolen by your son's friend, and used to murder someone, you are charged with accessory to murder! If we had these types of laws and enforced them, then gun owners would get a lot more serious about taking care of their firearms and people who shouldn't be possessing them would have a lot harder time getting ahold of them. We also need to spend the money to enforce laws already on the books. States (and mine is one of the worst at this) need to pony up some financial resources to fund adding the names of committed persons to the federal list of those not allowed to purchase firearms.
These types of regulations are reasonable under the circumstances, are very likely to reduce gun violence over the long term, and are not an intrusion of anyone's 2nd amendment rights. An assault weapons ban is an intrusion of the 2nd amendment, and is not likely to reduce overall gun violence, as evidenced by the study I cited above. Lets dispense with the emotional responses and try to get to the heart of the real problem. And the real problem is that too many gun owners allow others easy accessibility to their guns, which results in a large percentage of the gun deaths. If the woman in Newtown had her guns secured in a safe and her son didn't have access, she and a lot of kids would still be alive today. Likewise, if her son had been in a mental hospital where he obviously belonged, or at least on some effective meds, same result. Less unnecessary deaths.
Thoughts?
