And we already have a law that states that.
Wanting more laws that do the same thing is not common sense
How about one that actually works?
If something isn't working YOU FIX IT.
You don't say, "Hey, my fridge isn't working and all my food is spoiled. Well, might as well just enjoy food poisoning!"
No. You throw out the bad food and you get a fridge repairman in there, or you get a new fridge.
Same thing here. Our gun laws are BROKEN. We need to fix them.
Now go away.
