I have two problems with it.

1) I think it's wrong and idiotic to desecrate a body. I think it's wrong because the dead may have innocent family members that attach a sentimental or religious value to the appropriate care and burial of their dead, and they will suffer needlessly from ill-treatment of the corpse. It's idiotic because, wtf dude, it's dead. What're you hoping to accomplish? All you're going to accomplish is looking like a jackass and that's a pretty stupid reason to do something.

2) I think it reflects poorly on the military of a country that likes to sell itself as the Flagship of Freedom and Civilization to act in a barbaric and childish manner like this. It also reflects poorly on the intelligence of our troops that they recorded a video of it because THAT'S never going to come back to bite you in as in this day and age.
