Good memory and catch, athelass.
...What the evidence does point to is that SSgt. Wuterich failed to exercise due care in his own actions or in supervising his Marines. ...
I'm wondering if this is as much about who was in charge as it is about who killed the Iraqis in House #2. It doesn't quite say that, but Ware does point out his belief that due care was not excercised fully in supervising his Marines. IOW, the buck stopped with SSgt. Wuterich.
Yes, the squad leader has greater accountability. The pursuit of the runner from house 1 to house 2 was on SSgt Wuterich's order. Whether that was a reasonable command, and whether the Marines observed fire discipline once they got to house 2, will be the center of a trial.
It's interesting to note that, in the Tatum recommendation, LtCol Ware found Mendoza not credible. Mendoza is the government's only witness against SSgt Wuterich for house 2. Mendoza is such a weasel that he alone could create reasonable doubt.
