But acquiring guns on the black market isn't going to be an option for many types of shooters. Like the mentally challenged killer in the Sandy Brooke shooting.

But acquiring guns on the black market isn't going to be an option for many types of shooters. Like the mentally challenged killer in the Sandy Brooke shooting. Here in Japan, there is of course a black market for guns. But basically the black market is so prohibitively expensive. This eliminates a huge swath of the population, mainly everyone that isn't rich. And again, I don't dispute that there are other ways to kill. Only that most of them are vastly less efficient, reducing the possibility of sprees like those we see in the US. Also 600 deaths is nothing to scoff at. Hard to know, but my intuition is that 600 deaths is higher than the number prevented by guns.
