Look at swiss, everyone has weapon there since recruit army time, and look at rest fo europe (Czech, Slovakia, Germany...). Also, such countries are prone to government terror any time, or some other strong group terror (mafia etc).
How each culture handles react to liberal gun laws varies, but US is in a class of it own. So you can't can't compare ratios: gun crimes rates / liberal law with another developed country
Banning knives would make it even worse as less parents or teachers would be willing to tell kids about such consequences. And bad guys don't care about laws anyway. Bad people (kids, teenagers, adults) will carry weapons whenever it is legal or not.
Humans by nature need to be told certain lines should not be crossed everywhere- at home, at work and the by law.
Since Laws/Legislation is part of what creates or forms a culture in a country, Whatever death-by-gun-crime rate exist in any country can be improved by stricter laws
Banning weapons of any sort can never eliminate crime but would significantly minimize it, At least statistics between countries verify that.
I'm quite happy to live in a place where the unequally desperate folk perform muggings without weapons. Heat-of-the-moment suicide and homicide unfortunately still occurs, but took a massive dive when we got rid of most of our guns. Most people who attempt suicide don't attempt it a second time. Farmers here are still allowed to own guns for pest control, and many of them unfortunately succeed in using them on themselves the first time... in the rest of the country, those stats have improved with such easy killing tools becoming so time consuming and/or risky to obtain.
... and for these reasons too
You know that gun-related violence and mass shootings in the US are decreasing in frequency, right? Don't let a sensationalist media desperate for attention shape your entire worldview. Hodgman hypothetical scenario does actually exist in some places. The area where I live is approx. 85% owner, and the only incidents of gun violence in the last 15 years was one hunting accident and one shooting of an out of state by another out of stater. If guns were as evil as advertised, I think the numbers would be somewhat higher.
Your comment regarding guns being addictive is a non sequitur. They're just a tool. No more addictive than a garden rake.
I think that such incidents of violence speak more to the character of the people involved, than the nature of guns themselves.
Actually i think its the opposite! I believe gun crimes is seriously under-reported. If a single person or 2 people are killed in a gang related shooting, because it such a common occurrence and only few people are killed- it never makes the headlines
You say guns are tools, but what are these meant to be used for? (apart from a small percentage of riffles for game hunting/shooting animals)?
In the heat of the moment when anger boils/ depressions/whatever... because a guns is easily available it is used - it seems like, I will take it out on others is a sweet revenge
Over here, in the spur of the moment ... you could punch your walls , throw chairs around ... because no guns are available . That's the DIFFERENCE
