From another article back in 2015:
" The massacre left 14 civilians dead and at least 17 wounded. “None of the victims was an insurgent, or posed any threat to the Raven 23 convoy,” the government said, in a sentencing memorandum filed to the court on 8 April.
The memorandum contained quotations from relatives of those killed in the attack, including Mohammad Kinani, whose nine-year-old son Ali was killed. “That day changed my life forever. That day destroyed me completely,” Kinani said.

Also quoted in the memorandum was David Boslego, a retired US army colonel, who said that the massacre was “a grossly excessive use of force” and “grossly inappropriate for an entity whose only job was to provide personal protection to somebody in an armored vehicle.” "

Hopefully they are tried and convicted again.  Crazy.
