In epidemiological terms, they consider guns as a disease. Initially, HIV was considered a gay plague . Stop anal sex and lock up gays and that will end the problem . This is obviously ridiculous. AIDS is a blood disease, a retrovirus, not a disease caused by anal sex.
Anal sex is merely one means of transmission.
The same is true for firearms. In the epidemiological sense, firearms are not the disease, they are a means of transmission. Violence is the disease. Indeed, statistically, firearms may be the least efficient means of transmission of violence. If we consider violence as the disease, violent crime falls into place.
