This is why Canada must get out of Afghanistan now.
From The Guardian:
US soldiers 'killed Afghan civilians for sport and collected fingers as trophies'
Soldiers face charges over secret 'kill team' which allegedly murdered at random and collected fingers as trophies of war
Twelve American soldiers face charges over a secret "kill team" that allegedly blew up and shot Afghan civilians at random and collected their fingers as trophies.
Five of the soldiers are charged with murdering three Afghan men who were allegedly killed for sport in separate attacks this year. Seven others are accused of covering up the killings and assaulting a recruit who exposed the murders when he reported other abuses, including members of the unit smoking hashish stolen from civilians.
In one of the most serious accusations of war crimes to emerge from the Afghan conflict, the killings are alleged to have been carried out by members of a Stryker infantry brigade based in Kandahar province in southern Afghanistan.
According to investigators and legal documents, discussion of killing Afghan civilians began after the arrival of Staff Sergeant Calvin Gibbs at forward operating base Ramrod last November. Other soldiers told the army's criminal investigation command that Gibbs boasted of the things he got away with while serving in Iraq and said how easy it would be to "toss a grenade at someone and kill them".
