Did you ready the article? McBride initially posted on his personal blog, which caught the attention of ABC journalist Dan Oakes. The information was leaked to Oakes and the ABC from there.
My reading of the article was McBride didn't initially think there were war crimes committed but:
ADF leadership alleg(ed) that SAS soldiers were being wrongly accused and illegally investigated for war crimes.
“If there is political bullshit going on against soldiers, and it doesn’t matter whether they’re SAS or not, you need to stand up for it,”
McBride didn't think war crimes had happened which is why he asserts that the soldiers were being wrongly accused and investigated. Oakes disagreed.
Now the question is, why is Oakes making this allegation allegation against McBride if it's not true?
Is honestly pretty unambiguous wording.
And the other evidence against your claim is, why would McBride had been pissed off by the ABC's reporting of his leaked files? If you were right, the ABC's angle would be completely aligned with McBride's. Why would Oakes allege there was disagreement there?
