Every country I have ever visited has laws that ban guns except for genuine usage such as hunting, sport, or for members of the armed forces. And in each of those countries, those with a firearms licence must renew it regularly, be trained especially on its use, prove that they own the gun for genuine purposes, keep the gun in a safe and secure location when not in use, and must take regular training and undergo mental health examinations when they renew their licence.
In every single one of these countries, mass shootings, for all intents and purposes, simply do not occur.
The rest of the world cannot be wrong.
Statistically, here are some countries that are safer than the USA:
South Africa, Niger, Honduras, Nicaragua, Brazil, Armenia, Thailand, Turkmenistan, Guatemala, El Salvador, Algeria, China, Uganda, Mozambique, Cuba, Haiti, the Dominican Republic, Bolivia, Jamaica, Tunisia, Bosnia, Rwanda, Ecuador, Peru, Jordan, Sierra Leone, Albania, the UAE, Ghana, the UK, Indonesia, Mongola, Lithuania, Uraguay, Spain, Botswana, Germany, Norway, Sweden, Denmark, Hungary, Belgium, the Netherlands, Australia, Ireland, Switzerland, Japan, Canada, Austria, Portugal, New Zealand and Iceland.
And that isn't even all of them. But notice, in the list which can be found
here, that every single EU country ranks above the United States for safety, and yet nearly all of them have no border controls and allow free movement between them. The EU has a population about 2/3 larger than the population of the United States, yet has only 5,200 homicides in its entirety last year. By contrast, the USA had that many homicides
in just California, Texas, Florida and Illinois, which
collectively have a population of just 95 million.
That is a homicide ratio of EU to USA of about 1:6. Or put another way, you are 6 times as likely to be murdered in the USA as you are in the EU. Why is that?
Well, the USA experiences the vast majority of its murders via firearms, as you can see in the graph below:
Removing guns makes murder more difficult. This is why countries with strict gun laws, for example like those in the EU, do not have as many murders as the USA does. It's simple physics: firing a projectile from a distance at supersonic speeds is far easier than getting close enough to use a knife or a pillow.
In the EU, guns are incredibly difficult to obtain, and being found with one usually carries a lengthy prison sentence. Yet, our borders are, via car, bus or train, every bit as open as the US's internal state borders are. Our population is greater, and our murder rate is significantly lower.
Guns and the laws surrounding them, are a large part of why this is the case.
