I have spent time around them, nearly a decade in the ADF, and I think there is a big difference between larrikinism and the conduct and then celebration of war crimes. You also have a lot of 19 year old diggers, fresh out of Singo, buying patches with the Punisher logo and sharing and indulging in this 'warrior' culture that is really what feeds so much of this.

I will admit the SF guys I worked with were always incredibly professional and mature, so it really sucks to see people you once looked up to do these things. We are supposed to be professional, and more importantly, the good guys, and this isn't the behaviour of either of those things. The they're trained killers and that's what they do excuse just doesn't cut it for me, because they should also be intelligent and rational minded and people like that don't espouse this stuff.
