Guns wouldn't be banned or restricted if the powers-that-be didn't fear them. 100 times more Swedes die from tobacco than from guns, yet anyone who is 18 can buy tobacco without restrictions. Why? Because tobacco is no threat to the powers-that-be.
If our health and security would be their no. 1 objective, they would of course ban things in proportion to what harm they cause, but they don't. They ban or restrict them in proportion to how much tools of power they are.
Freedom isn't measured in guns only, of course.
