That may not be a good idea in case of fire.
The blatantly in your face obvious truth is that Norway, Sweden, Finland, and Switzerland have the 2nd, 3rd, 4th, and 5th highest rate of gun ownership among civilians. So, according to your logic, they should have the 2nd, 3rd, 4th, and 5th highest rates of school shootings. They don't. Mexico comes in 2nd behind USA. It is obvious that there must be other factors in the school shooting rate besides "GUNS!!!
Yes I am aware USA has the highest rate of school shootings. The point of this thread is, what other factors may be involved in this disproportionate rate of school shootings?
Let's compare Israel to get a better understanding. Everyone in Israel, male or female, must serve at least 2 years in the IDF. That is ~100% of the population, except for certain exemptions. If you ever visit Israel, you may see soldiers carrying guns as they walk down the street, women with a rifle slung over their shoulder at the grocery store, and it's totally normal there. Even USA does not have this rate of gun use. The numbers are skewed because these graphs only look at civilian gun use, not military. So when ~100% of the population is military, that leaves very few civilians with guns, because there are very few civilians at all. Yet, despite that fact that Israelis are far more likely to be carrying a gun at any given time than Americans, Israel has a much lower school shooting rate.
