@chillanarchist01@Bernard well there are people with degrees in psychology whose job is exactly to assess whether someone is mentally fit to hold a tool for murder. I’d trust their experience. Most if not all the other Western countries have tight background checks when it comes to gun licenses, and nobody seems to complain.
Is the right for a nutcase to buy a gun worth more than the right of a kid to grow up in a safe school environment without exposure to violence or tools of violence?
