Schoolchildren are not murdered by guns, they are murdered by people. People who were arguably broken by the school system. Banning or restricting guns is also just politicians trying to pretend they're actually doing anything. Schools have been "gun-free zones" for 33 years. This disarms potential victims instead of protecting them. Violent crime and mass shootings do not correlate with gun ownership within the US, and per capita mass shootings are higher in many countries with more restrictive gun laws.
