Acts of brutality such as these are never justified - no matter what the circumstances.
Tell that to the governments of the world they seem to think it can be justified, say, defending some ideology called freedom be it what ever they call freedom.
I personal do not condone violence and might be loosely termed a pacifist for myself but in terms of what governments need to do survive I'm not nieve as to the dangers to stay in power. I know human nature and what the other guy is capable to do to gain power. So I can't say I agree with this statement.
A bloody good example of what the navy calls "The Jack Club"
i.e. "I'm all-right, Jack. F$^k You!
How is it a good example with what ever you call it?
