As Magox said, we are expected to behave in a certain manner (and I agree with that expectation.) We are supposed to be civilized. We killed them- we won. Pissing on the dead bodies, whether is is seen or not, is going for something beyond the victory. You can argue the value or non-value of public executions all you want, but once the person is dead, it should be over. Yes, if the Seal Team did that, they should be dishonorably discharged, whether we saw it or not.
I will admit that I am not the most eloquent person in the world......
