Not good at all

Our situation in Afghanistan might improve if we can manage to stop doing shit like this:

U.S. Special Forces killed six Afghan police and wounded at least 11 early Wednesday in a case of mistaken identity after the police fired on the Americans during an operation against an insurgent commander, officials said.

How many times has this happened now? I don't mean to play armchair general, but if you keep accidentally killing civilians and your allies it starts to look to the afflicted group as less and less of an accident.
