Trained To Kill

At least 121 Iraq and Afghanistan war veterans have committed a killing or been charged in one in the United States after returning from combat.
There have been 349 homicides involving all active-duty military personnel and new veterans in the six years since military action began in Afghanistan, and later Iraq.
About a third of the victims were girlfriends or relatives. All but one of those implicated was male.

Let's not forget about the over 1,165,204 people killed by the US occupation of Iraq plus the over 12,000 killed in Afghanistan
