in short if you dont want to read it a US sniper used a koran as target practice and then the iraqi police found it a few days later. And as expected there is outrage from the muslims.
Some muslims need to get over themselves. An incident as small as this should not threaten the political relation ship between the US military and its allied tribes.
Yet its ok for them to denounce other religions, make death threats over cartoons and burn our flag. Sure the act might have been unproffessional or insensitive but really, its a book, get over it. Its not like theres only one copy.
