To me this is very disturbing.  55 civilians were killed?  I mean I get that they killed some bad guys too, but to me it is not worth sacrificing so many innocent lives just to kill a few bad guys.  U.S. troops were killed too.  This whole thing is just terrible and tragic in my opinion.  IT sounded like some protocol was not followed either, which makes it even worse.  I think we need to mind our own business and get out of there honestly.  We have enough issues with our own country to be over there contributing to issues in others.
