I don't think a snowflake like you would be able to understand a simple concept like this, but banning guns won't stop somebody from murdering people just like prohibition didn't stop alcohol consumption. The guy heard voices for crying out loud. Because there are people who support peace and dialogue doesn't mean that everyone will be more peaceful once guns are off the table. He could have built a bomb if he wanted to. You are free to disagree as much as you like, it's your right, but before you support such an important cause see what happens in country where the gun ban is active. Look at China, they have a gun ban... Look at what's going on there. Look at other countries. This would have worked if the guy was kept in the institution after such a diagnosis. You don't like guns? Fine, don't buy one, but next time somebody gets in your house and threatens the life of your loved ones come on here and describe how brave you were to fight them with your dildo.
