I'm not saying it is based on recent events, and you have to admit that those countries have only banned their guns in the last 20 years. It still remains to be seen how long they last, no offense intended.
I couldn't speak to all those countries with any semblance of credibility. I've lived in New Zealand and Australia, so I'll limit to those.
Changes in Australian gun laws were in direct response to a massacre in Tasmania. This massacre was conducted by a gunman using an AR-15 and a FN-FAL.
In terms of the gun controls put in place, they focused on semi-automatic weapons, or automatic pistols with magazines of greater than ten rounds, as well as larger calibre guns (over .38 I think). The only grey areas I recall were around semi-automatic shotguns, but I'm purely working from memory on that.
It was specifically intended to target private holders of weapons capable of killing in large numbers. There were provisions for farmers, etc, to be exempted, and hunting rifles generally, as well as small calibre revolvers, etc (defensive weapons) were not targeted.
Since 1996, there have been no gun massacres in Australia (gun massacre defined as 4+ killed). It's not 50 years worth of data, it's only 20, but it's still informative. There had been 13 in the 18 years before that.
In terms of the longevity of the laws, it's an interesting one. It appears they have been watered down slightly in some states (these are state, not federal in nature, and were implemented via common accord). Again, semi-automatic shotguns seems a specific area of argument.
We haven't banned guns. We tightened controls. There were controls prior to 1996, and there are controls after, but they become substantially tighter around weapons capable of being used as effective offensive weapons against crowds.
The Kiwis have less rigid restrictions than us. A lot less from memory, and there are some that don't have much control at all, dependent on their classification. To me, using them as an example is more just that gun control isn't 'all' or 'nothing'.
Give it 50 years, and then we will have some data to work with. There are plenty of examples ancient, modern and in-between; where technology is taken away from citizens in order to subjugate them whether it be mill stones, swords, furnaces, encryption or whatever. The same basic argument plays out: Technology X is 'Evil' and corrupts, and so we cannot allow the poor middle class to keep it. Only the wealthy and the responsible ought to have Technology X. I see the banning of guns as an edge case but still a similar case, as its a technology that can be used in armed rebellion. Usually other technologies pose different threats, but they are treated the same way. They are evil because of blah, and their use is restricted to the new best class of people.
The argument here was nothing about guns corrupting. The issue was the ability of a single citizen to kill fellow citizens in an efficient manner. We preferred to put controls in place to slow that down. Hopefully, the thinking goes, next time we wouldn't lose 35 dead, and have the gunman being better armed than the first response police.
Would you see unfettered access to all weapons as a positive?
Oh, yes; but hopefully that is going to subside. I'm sick of traffic lights taking my picture. Its nobody's business where I drive. Ultimately the country is or was headed in the direction of push-button knowledge of each voter's choices in the ballet box. I'm telling you, you have things to worry about if you're betting the USA is not dangerous. We're certainly dangerous, and you've already witnessed our govt. manipulating voters. Its plain as day that there are no scruples about it, as senators of parties have colluded to draw the craziest crooked lines around voting districts, halted govt., filed ridiculous lawsuits, started wars without even declaring war and done various kinds of international mischief. Money has been declared = to speech by the supreme court. I do not see all of this surveillance as an isolated thing or as a conspiracy either. I just don't think we're 'Safe'. Our republic is not safe any more and is precariously close to some horrible big brother of the sort that wouldn't be possible 30 years ago. If that doesn't scare you then I'm happy for you and give me some, but you'll pry my gun out of my cold, dead hands.
It's not that I trust the US government. I was merely making the point that the implication of gun control laws by a government doesn't seem to particularly correlate with the likelihood of a government to be corrupt or partake in undue surveillance. It was a repsonse to your earlier comment.
I am talking about long term, not short term and not just guns but also technology, privacy, education, and ownership of things. These are all related things. They are all 'Guns' in the government's eye. They are all things the government will tend to take away over time. For example, the govt. will restrict what you may build for your own safety. Its not a conspiracy, but you can't build a house unless you meet certain codes, have it inspected by a govt. spook. That is an example of how govt. by nature gradually restricts what you can do but expands the ability of the wealthy to do things. It is one of 10000 things that build up over a century which eventually divide wealthy and poor. If you are poor its a problem for you to pay for someone to inspect what you build, so you cannot build if you are poor. If you are poor the govt. does not trust you, etc. The govt. does not trust you, and so it will restrict what power you may have. It will try, eventually, to keep the children of poor people, poor, etc. It will try, eventually, to take away rights in the name of protecting some aspect of national quality, such as divinity or pride or awesomeness or destiny and so forth. That's not fantastical reasoning but historical, repeated tragedy.
Again, though, extrapolating in the manner you are appears hyperbolic to me, and doesn't appear supported by modern, democratic examples. Our laws aren't about the government subjugating citizens, they are about protecting citizens from each other. Governments represent the people in an effective democracy, and the people wanted gun controls.
