Painfully hilarious. I desperately wish some of your fellow countrymen would actually read what Jesus really said about such matters ("Those who live by the sword will die by the sword" springs to mind).
In the UK, we had a horrifying school shooting in 1996, in Dunblane (the school where a certain Andy Murray was, as a child, as it happens). Our already strict gun laws were massively tightened as an immediate response to the incident. There hasn't been a school shooting since.
But no, banning guns solves nothing, apparently.
