(1) Should a gun totting tyrannical minority of 5% be able to ride roughshod over the wishes of the 95%?
I'm a believer in natural rights and the non-initiation of force principle, in that every individual has, inherently, the rights to everything within their domain, and that domain extends out in a metaphorical sense until it hits someone else's. The government is both an arbiter and a grand actor in the web of relationships created, and as such it needs to be held to strict limits to not -needlessly- encroach on them. The government, by default, violates non-initiation because it operates under an implication of coercion, therefore it should keep its number of coercive actions to a minimum to maintain legitimacy. In matters relating to natural rights like the ownership of property, the government is- or at least should be- very limited in its reach, and in the US we have the Second and Fourth amendments to guarantee this. If your theoretical split was 99.5/0.5, it would still violate the natural property rights of the individual, and thus would not be ethical. At the same time, the rights of the gun owners thus protected end completely when they encounter another individual, or their rights. Once the gun owner violates those rights, it is then ethical to act with force, and as much force as is necessary to completely solve the problem (proportionality). The problem with making laws is it infringes also on the rights and lives of innocent people, those who have not committed any crimes. As I pointed out before, murder is already illegal. If that isn't deterrent enough, what do criminals care about breaking a few more laws? Any laws you put on top of it are both redundant and encroaching on the natural rights to a person's private property. The government should tread exceedingly carefully where these laws and rights are concerned.
(2) Should we now decide not to pass any new laws about anything anywhere as all points have already been discussed and decided?
Ideally, the use of passing laws wouldn't be something done willy-nilly and a great deal of debate would go into them from both a systems design standpoint (as government is a system, as any other) and philosophical standpoint (because political differences come down to philosophy- the nature of man vs man, man vs community, man vs state) and laws would only be passed in the direst circumstances. Imagine if government was run not by politicians but instead by programmers, engineers and philosophers! In my answer to #1 I already pointed out that government is a good thing, but should also be a very limited thing. I support many community-based and voluntary solutions, and I see this everywhere in daily life. I volunteer at a food shelf, and there we operate much more efficiently than most any of the government's food distribution/discount programs; we're the first stop for most of the people on food stamps and we don't even charge them said food stamps, they simply take food. I think at a community and town level, people can be much more effective at regulation that at the federal level.
Part of this is regional differences as well (and I am willing to believe, in fact, that the ENTIRE difference in statistics between the US, UK, and CH originate in regional differences, as you say, which is why when I plotted my detailed analysis I only did it between US states- more accurate and relevant comparison) and because of this different regions need different solutions, some legal and others moral and community in origin. The US is comprised of many different regions, and one blanket 'solution' would not be nearly as effective as solution at the community level, and at the community level it could be judged whether or not a solution is needed at all.
But those are philosophical points. I also take issue with the proposed laws from a system-design standpoint. As I'm an engineer by trade, it is in my nature to look at things as components in an overall system, and the government is definitely a system. As my scatterplot showed there's no correlation between gun control laws and % firearm homicide rates, therefore it can be concluded the laws do not impact those rates. In fact when I put a trendline to it, the rate INCREASES slightly with further legislation, but I believe this would be because areas that fall victim to higher rates are more likely to legislate against it (and the data delay between my sources likely emphasizes this relationship), whereas in areas where it isn't a problem few laws are needed- two of the three states with a control score of 0 (effectively no control) are in the bottom ten states of % rate of homicides by firearms.
If the proposed change to a system would have little or no effect to the problem the system is experiencing, then logically it is not the appropriate change to make. If you cannot find an EFFECTIVE solution to the problem the system is experiencing, then you should either not change the system at all, or if the problem is crippling the system, you should redesign the system. Gun control laws or the lack thereof are not -crippling- the nation (not that the issue itself cannot cripple a nation, I'd argue that with the various African nations this problem IS crippling, it just isn't crippling the US) so the system does not need to be REDESIGNED around this flaw. So until we find an -effective- course of action, from a systems design standpoint we should not act at all. Again going back to how laws are grave, serious things, it would be a frivolous law if it did not achieve its own aims, and I believe I have demonstrated that in the case of America, gun control laws would not achieve their aims.
(3) Do you think gun insurance could address some of the problems without violating the constitution?
@Semck, Maniac; it seems your disagreement is one of semantics and not at the issue at hand. Either way if we treated firearm policies like automobile insurance, I think it would be an interesting measure for assisting victims of gun crime. When we get down to it however I doubt that criminals will insure their guns, so this would basically amount to just another charge on their records when we bring them into court. As I can't see the law being effective, I'd instead opt to strengthen current procedures such as background checks when buying firearms. There's many holes in the current system and I feel those holes should be patched before we go looking to add more onto it. There is a large debate-within-the-debate inside this issue about the appropriateness of a national firearms registry. While that has it's own flaws I feel that as long as an innocent owner is not held liable for damage by stolen equipment, that might at least be an appropriate target for a cost/benefit analysis and debate over the ethical implications inherent in its application.
