Suicide kills 47,000 men, women and children a year. Society shrugs.

If a killer roaming America left 47,000 men, women and children dead each year, you can bet society would be demanding something be done to end the scourge.

Well, such a killer exists. It's called suicide, and the rate of it has steadily risen.

Yet the national response has been little more than a shrug, apart from raised awareness whenever celebrities — fashion designer Kate Spade and renowned chef Anthony Bourdain, to name two this year — are tragically found dead by their own hand.
