WTF ARE YOU GUNNA SHOOT HIM WITH?!? A SLINGSHOT?!
I'm simply not going to shoot him.
1.Changes are he is in reality a family member.
2.If he has a gun, he may rob me - I call they police, they catch him, I probably get my stuff back. If they dont, well, I still live. Guns dont protect against bullets. If a robber sees me with a gun in my hand, what will he do? Wait until I shoot?
3."Illegal firearm" - when firearms are banned, that happens far less often than you might think. If I want to break in a house that has no firearm, what do i need one for? If he wakes up and catches me, i simply run, he cant shoot me in the back, can he?
Why engaging with possible deadly, organized criminiality to purchase an quite expensive gun (what, you think smuggling is for free?) for basically no benefit?
Criminals like Bankrobbers will most likely still somehow get their weapons, thats true.
I also have to agree that, if there would be a nationalwide (enforced) gunban, it would take many years for it to have notable effect, until most firearms disappeared from the society.
During this time, things probably would get worse, not better.
