61% of killings are classified as suicides. Everything that can be done has been done to reduce the suicide rate in America, but some folks are just weak. And I do not mean that in a derogatory manner, just an observation. You also have an increase suicide rate after wars. Over 50K died by suicide after Vietnam, and there has been thousands of suicides since the fighting in the Middle East. Some of the blame for veteran suicides is related to how they are treated when they return home. Not to cast total blame but liberals didn't help any when they protested in the streets and disparaged our returning military Vets. Other reasons for suicide are financial hardships, loss of close family members, divorce, substance abuse, untreated depression, loss of employment, persistent physical pain, etc. You can assist victims of these traits, but you can't alleviate suicides altogether. A gun is just a tool for these actions. If not a gun, then a sharp object, chemicals, etc.

If you could get rid of ALL suicides and gang slayings by gun in America, the overall statistics for gun related deaths would be substantially low, compared to death by overdose, by doctor, by automobile, by falling, by drowning, etc.

There has already been a lot of effort put into mental health, so any political action at this point is all just campaign motivated fluff.
