Wow, that's a powerful letter of a personal experience.   It doesn't mean that all people with guns would have the same end to the story.  

It's just important to know that a gun does NOT assure your safety, we have an example.   We also have the many accidental deaths by gun and a record of suicides enabled by guns, (the most deadly method of suicide attempts).   

*I had a close friend who committed suicide, party because of depression caused by his deteriorating marriage, party because suicide was real for him, having two other male member of his family do the same with guns in the past.  Guns were a 'solution' to his pain. 

It is unfair to say that the person who does not own a gun is not being responsible for their families safety.   It may well be the opposite.

A gun fired in fear or anxiety, doesn't often give you a second chance.

I support the right to own a gun.   I do not support an unregulated market.
