Americans can keep their right to bare arms. But those arms don't have to be the kind of arms used in these shootings. Let them all have a 1777 pistol not a 2022 rifle and see the effect that has on mortality rates. Problem solved, no more school shootings. Because the shooter will get maybe one or two shoots at best.
We don't have a gun ban in the UK we have stricter laws on gun control, which is not the same thing. There are many people with a gun license. But these are harder to get, involve stringent checks and the types of weapon are restricted. America could absolutely improve gun controls in the same way over time and see a massive reduction in these kinds of incidents. Would it eradicate Them overnight? No. But it would improve the number and severity of incidents pretty damn quickly.
When your kid keeps drawing on the wall, you don't hand them crayons more easily, do you? No. You take the crayons. You hide the crayons. You only give them crayons when they have some paper to draw on. You make the crayons harder to get. You give them alternatives, why don't they play dolls or do jigsaws? They might still get hold of a crayon and draw on the wall, but there will be less crayon overall.
These teenagers are reaching out in desperation for something to help them, and instead of finding connection, community, therapy, mediation, love, a mentor, a parent, a friend, a priest, they are finding that a gun is in easier reach. But what if it was harder to get to a gun? What if it was so difficult to get one that by the time they did they had had a chance to make a different choice. They had a chance to fix some of their feelings and problems and never got to that gun at all?
The easiest intervention is to create distance. It is so much easier for a kid to not draw on the wall if they don't have any crayons. So much easier not to eat all the cookies if you don't buy any cookies. So much easier to not shoot up a school if you can't easily come by a gun.
The problem of disenfranchised young men, incels, racists etc. Is not unique to America, but the shootings are. And that can only be because of the availability of guns, and not just any guns but the kind that are largely restricted elsewhere in the world.
