Fine.
You've just taken the first step in treating the problem of gun violence as a public health issue and have taken the perspective that it has epidemiological roots and therefore can be treated as a public health issue.
.
Like any other public health issue such as a viral epidemic, you have to eradicate the virus to restore the public to good health.
A few of the steps that need to be taken:
.
Take guns away from domestic violence offenders.
When a gun is present in a situation of domestic violence, it increases the risk the woman will be killed fivefold.
.
Require that lost or stolen guns be reported and guns in homes, especially with children present, to be safely and verifiably secured. A child is unintentionally shot by a gun every 34 hours.
.
Background checks work. Let's make them universal.
.
But the real reason that the gun homicide rate is 25 times higher in the US than any other high-income countries is that there are just too many guns in circulation.
