It’s not a good point at all. That’s like saying “Well, criminals will rob banks anyway, so why bother making bank robbery illegal?”
It’s not a good point against banning guns from civilians. But to me, it makes me question how we can make it harder for criminals to get guns since they can attain them so easily in an illegal manner despite any gun laws. It just seems like an element of our system that is leading to more violence and death and I wonder if there’s a way to help fix that within our legislation capabilities.
