I'm not contradicting myself. It depends on your definition of "American behaviour".
If you mean behaviour displayed by Americans. Than the are actions displayed by the people involved is "American behaviour". However that does not mean it is displayed by all Americans. Regardless of what Broda said, I doesn't even mean that displayed by all or even most of the US military, nor is it institutionalised or desireable with in the US military. Cripes they people are being charged and are probably going to jail.
I find what most people do when they present a statement such as yours tend to make the next jump, "Well, they aren't true Americans.". Or, "That's not real American behaviour. Thus changing the definition of what an American is to disallow the characteristic, but turning the definition into something meaningless, and nebulous to fit thier arguement. An American is simply someone that is a citizen of the US.
Batz, I'm not going to change my reasoning simple because you replace the world "American" with "Canadian". But I will point out that our reponse to the display of that characteristic was to have a full public Parlimentary inquiry, charge, try, and convict those involved and to disband the entire unit.
