Gun control solution
To be able to get a gun you have to be endorsed by at least 5 other gun owners. No parent hands a gun to their child if they aren’t able to handle it. When you’ve had at least 5 endorse you that means they trust you to have a gun. Your gun endorsement costs 25 per year and can be sold if you don’t want it to someone for any price.
If someone is convicted of a crime with that gun then the people responsible for that gun get revealed. The more guns you sponsor with out convictions is your ranking.
