Violence Costs in monetary terms

Since money talks with policy makers, this research ought to encourage investment in 'conflict resolution' within society, which would start to change culture, I hope, for wider conflict. Apparently the costs of violence in the USA rival the costs of hurricane Katrina.
"researchers found that most of the costs of violence stem from males and young adults. Sixty-eight percent of the costs from assaults and 63 percent of the costs from self-inflicted injuries were in males aged 15 to 44.
“The most burdensome category is among young males who are victims of assaults with firearms,” Corso said. “So if you want to prevent those costs from occurring, you need to focus on prevention in that particular population.”
Other findings from the study include:
* Most of the $70 billion in costs associated with violence were from lost productivity ($64.4 billion), with the remaining $5.6 billion spent on medical care.
* Americans suffer 2.2 million medically treated injuries due to interpersonal violence annually, at a cost of $37 billion ($33 billion in productivity losses, $4 billion in medical treatment)."
