But a lot of people won’t. If you make it more difficult or more expensive to break the law a lot of people will have to resort to easier and cheaper options that will reduce the body count. When I started in law enforcement in the early 1980’s it was rare to encounter anyone with a long gun or for that matter a semi automatic handgun with more than six shots. Most criminals carried revolvers. A revolver can kill you but it doesn’t have the mass killing power of what’s available today. Even if we start today it will take some time to impact the supply and the price but eventually it will. On a related note, do you remember when anyone could walk into Southern States and buy as much dynamite as you wanted? I don’t either but my grandfather does. We finally started having to regulate that cause people were blowing up buildings. Took a while to get the supply down but eventually it did.
