Andrew, This sucks and I wish we were out of Afghanistan but we aren't out of Afghanistan so the soldiers, marines, airman, and swabbies have to do their job. These accidents are tragic and we wish they wouldn't happen. The problem is that those we are forced to fight (by the command of our elected civilian officials, yes, that includes Obama and his surge) don't wear uniforms or stay on military bases. They hide amoungst civilians, dressed as civilians, and act like civilians. When the target isn't clear these kinds of mistakes are inevitable. Those who are truly at fault are the native Afghani insurgents.
