I'm not sure I can offer a valid opinion on the hypothesis. My own approach to RKBA differs from the idea of promoting RKBA as a social engineering scheme; my primary interests are the ability to protect myself and the pursuit of a hobby/interest that causes no harm to anyone. Here are some observations regarding your hypothesis:
Use of the word "hypothesis" implies a scientific approach, in which one of the chief tools must be statistics: what do the statistics tell us about gun ownership's relation to violence/looting/rioting? The mathematical science of statistics is a very powerful analysis tool, but it is also very tricky, because it is not intuitive, it is conceptual. In other words, what seems obvious "common sense" is often simply not statistically supportable. However, "common sense" will seem to indicate something else.
For example:
Gun ownership -- how many people have guns? Here is an oft-quoted source of data that people use for answering this question:
http://en.wikipedia.org/wiki/List_of_co ... _ownership
This study says that, for instance, in the USA, there are 88.8 guns for every 100 people. According to your hypothesis, a country in which a lot of people have guns ought to have a lower rate of riots/looting/violence, and one might make the case that, based on the high average of gun ownership cited in these data, the hypothesis is not supported.
BUT!
What are the data telling us? I submit, not much. It is telling us that there are 270 million civilian-owned million guns in the USA, and 304 million people. But does this tell me how likely it is that my neighbor has a gun in his house? Does it tell me that in my neighborhood of ~50 houses, 40 of them have guns? No, it doesn't say this at all. I have 22 complete guns (not including 2 of my older son's), which means that only 18 guns remain to be spread over the remaining 49 homes in my neighborhood. What this means is that, rather than some goon having an 80% chance of entering an armed home in my neighborhood, he only has a 38% chance, assuming that the other 18 guns in our neighborhood are each owned by different people. My suspicion is that, assuming that there really are 40 guns in our neighborhood, of which I own 22, the other 18 are located in far fewer households than 18, which lowers the chance that a criminal will encounter an armed household even further.
You see from my example how the statistical concept of the mean, or average, is of very limited value when trying to ascertain how "armed" any group is, whether we are discussing my neighborhood, city, state, or country. I have participated in sites where collectors individually own from 100 to as many as 600 guns -- I have seen pictures of such collections posted many times on boards. Individuals owning large numbers of guns like this is not rare in the USA. Given that few people could shoot more than one or two at a time, such large numbers owned by so few sharply skews the "firepower" in the average neighborhood or city.
The number of households owning a gun is one issue, and which guns are actually available for use in the case of the event would be another. Is the owned gun in a safety deposit box? An antique suited only for hanging on the wall? Does the owner even have ammunition for the gun(s)?
This doesn't even address issues like number of guns per city vs. guns per rural region, guns per section of the population, guns per inner city vs. suburbs, etc.
If you are familiar with studies, then you know that I have outlined what would be a herculean effort to assess the real threat an armed population might be to a civil disturbance.
A second issue would be assessing the nature of the threat of civil disobedience. As an example, let me cite three of hypothetical instances and consider them:
Example #1: You are a gun owner in London. You have a shotgun that you use for grouse hunting or skeet shooting. A riot of 14 and 15 year old looters breaks out, and when one comes to your home/store/place of worship, you stick the shotgun in his face and tell him to be gone, or else you tell him to spread-eagle on the sidewalk and hold him until the police arrive to cart him away in the paddy wagon. Or, maybe 4 or 5 of you and your friends, all armed with some collection of guns, protects your street from drive-by opportunists looking for trouble.
The threat of owned firearms here is going to affect and deter, I believe, opportunistic young people who are bent on hell-raising and who have put little or no thought into the possible consequences of what they are doing or why they are doing it.
Example #2: a large group of motorcyclists out on a lark enter a small town, where some of them get into an altercation with some townspeople. The altercation ends when one of the townsmen produces a gun and shoots the motorcycle of one of the group. The motorcyclists vow return and revenge, and later, heavily armed they return to wreck the town. A state policeman stops the returning gang and offers to take a couple members for a tour through the town. These members ride in a police car into the small town, where each adobe house is like a fort and just about every home owner is standing with a .30-30 at a window or door, waiting for the festivities to begin. (This is actually a real New Mexico story.)
In this case, the threat of owned firearms also has a decided effect. The motorcyclists are not mindless hoodlums and are motivated by a show of power and bravado, and back down when they see their vulnerability to some armed homeowners.
Example #3: In a Mexican town, a homeowner or group of homeowners is outraged by the depredations of a violent drug cartel. With whatever weapons they muster, they pose a threat to members of the drug cartel, warning them to stay out of the town.
In this case, the fact that the homeowners are backing their demands with firearms will almost guarantee their deaths. They may shoot or kill one or a few cartel members, but in such a case, the cartel will make sure that by one means or another, the homeowners are eliminated.
My point here is that different motivations constitute different threats, and not all threats can be lumped into the same bucket, where they are effectively dealt with by an armed citizen. In some areas, the threat may have to do with different ethnic groups. In some, it may be religious differences that motivate rioting. Politics could be the issue, based either on ideology or tribal affiliation. We could go through all of these and note significant factors to the ability of guns and the armed citizen's ability to protect himself and his family from harm. Northern Ireland (Roman Catholic and Protestant) and the former Yugoslavia (Roman Catholic, Orthodox, and Muslim) are both heavily armed areas, and people have been zestfully rioting and murdering each other for centuries in both areas.
My point here is that the motivation of the rioters needs to be considered -- not just the proximate cause, but the underlying factors, as well.
Regarding the riots in Great Britain, I am in conversation with a Scottish friend about them right now. He notes that the Scottish Nationalist leader has announced that the reason riots haven't broken out in Scotland is because the Scottish have "different values" from England. My Scottish friend expressed the hope that the leader would not have to eat his words. The situation in the UK is of great concern to me, because I strongly believe that we in the USA are sitting on a similar powder keg. I have heard arguments that propose trying to take away everyone's guns to fix the threat. I have no faith that such a plan, if it were even possible to implement, would have any effect of promoting public safety. On the other hand, saying that everyone being armed does not give me any more confidence that my safety would be ensured. If, for instance, a number of citizens had been armed with 9mm handguns in Mumbai, would the massacre have been averted? Or would the citizens have felt the same as the armed officials who threw down their SMLEs and ran? Sure, maybe someone would have shot one or more of the attackers -- if the death toll had been cut 20% or even 50% by such action, would I feel safer? (No, not really!) What about Norway, where one lone person did the deed?
In all these questions that I ask, I admit, trusting an ill-organized or unorganized group to protect public safety and my and my family doesn't really leave me with a much more secure feeling than trusting the government to do it. My own personal view of these issues, as it applies to me, is that life is always going to offer imperfect situations, and I am going to be faced with circumstances beyond my control to prevent. I feel more confident of my safety here in the USA than if I was across the border in Mexico, sure, but I know that bad things happen here in the USA, here in the state where I live (a state which has a "Castle Law" that legally allows me to defend my home with arms), the town where I live, and even my neighborhood. Since these are the cards that are dealt to me, I do feel more confident and safe having firearms to protect myself. While my motivation for firearms ownership is much more oriented toward fun and hobby than it is to protection and self-defence, these latter reasons alone are sufficient for me to demand the right to keep and bear arms, as I feel I am directly responsible for my own safety and protection and believe I am the best expert on how to get that job done.
I cannot say whether I answered your question or not. I suppose not, because I truly don't have the answer myself. Here in the USA, I hear lots of people talking big and puffing out their chest, bragging about what they'd do with their gun(s) under this circumstance or that. I have come too close, myself, to hope and pray (fervently) for anything other than being spared from such a trial. Thankfully, that's been the case so far. However, I have to tell you, when I hear people winding up and talking big about what they'd do, I cannot help but thinking that they are tremendous gas-bags, blowing about intellectually like a balloon that has been loosed. How do they know what they would do in any circumstance? How foolish it is to think that, if something happened, it would be similar enough to their vivid imaginations to protect them? I have lived long enough to understand the difference between "talkers" and "doers," and I also know that both traits seldom exist in the same individual.
For me, having the gun and the ammunition is primary, as is being able to use the gun as effectively as I can. However, having the determination to do what needs to be done is at least as important, since there won't be time to assess the situation when and if it happens -- there may not even be enough time to react effectively!
My bottom line is that I am 100% for the collective effort to implement, protect, and ensure the right of citizens to keep and bear arms. That's a big reason why I'm here. I wasn't around when those old Congressmen stood shoulder to shoulder to fight imperialism. Some people from other countries stood by you, but since I am only here today, what I can do is stand up for your RKBA rights as well as mine today, right now. I can't do or be much for either you or me, but I am here.
But even with all of this, the whole business of protection is, in my opinion, something that primarily applies to me, individual. It is an individual thought process and set of decisions much more than it is a movement, a political effort, or even a topic for argument. I will push for rights, I will encourage thinking and the sharing of information, I am for organization. But I've got to put my faith in myself and hope for the best, because the only person I have control over is myself. It's for this reason that I tend to avoid debates and their cousins, the arguments: They very very seldom change anyone's mind, at least as far as my efforts have been concerned.
