I'm sorry for your loss. I remember when one of my teachers committed suicide. It is difficult.
However we need to remind ourselves in these all too common tragedies, that the issue is guns.
In all my years as a physician, I never saw a treated an individual shot or killed by a gun owner while committing a crime. I did however, have plenty of cases where gun owner killed themselves or family member with guns on purpose or by accident. The accidental shooting of children is particularly hard to take.
We need to confront the nonsense about guns in this country, that has been spoken since its founding.
