From the USMC JTF6 Investigation Report:
Cpl Torrez said that the first time he heard Cpl Banuelos explain why he shot Mr. Hernandez was when they were interviewed collectively by a psychologist. He said that Cpl Banuelos simply said that "we reacted in a military way, we moved tactically, things like that. He said that -- he did say that Hernandez was aiming in on Blood and that's why he did it. That's the first time I heard that, was when we were with the psychologist."
It doesn’t matter if a few mex types, or a lot for that matter get killed in flakey circumstances, just as in 1918 what matters is thee is armed push back against invaders.
Large numbers of US military who are heavily armed and told their job is to guard the border and there will be no questions asked about what is done to accomplish that will end this invasion. That the USMC even has some staff bullshit agency called the G-6 is another problem to be dealt with.
