No judgment here in any way. I like guns too, they are a cool mechanical device and I worked with them for my whole career.
Cars, knives, hammers etc all have other useful primary purposes in society. Assault rifles have one narrow deadly purpose, and if someone who wants to kill as many people as possible in a short time has easy access to legally buy one, lots of people will die very quickly.
Assault rifles, high capacity mags and hand guns dont need to be eliminated, just restricted for purchase to the most responsible, properly vetted people.
Yes, crazy people will then go to the next easiest available long gun to kill people, but I can tell you the success of the tactical approach to taking out an active shooter who is using a bolt action rifle or a shotgun is much better than the shooter who has 2 shoulder slung assault rifles with a bag full of high capacity mags and a couple loaded .40 call hand guns for backup. And he cant do the same amount of damage with a normal long gun.
Define an "assault weapon"?
People give these wacko shooters too much credit. These crazies are not tactically trained operators with combat or CQC training.
Responses should be swift and deadly. Don't wait. Most of these shooters won't know what to do when attacked by armed persons/professionals.
