There is quite a bit more to this sad story than most sources are reporting. They did wrong and good guys died, and I am not unpatriotic, anti-military, or anti-Illinois Air Guard to say that.
I believe they need to justify their actions at Courts Martial. I don't prejudge them guilty or innocent but I believe they both have earned the right to be tried by a jury of their peers.
BTW, this was SOP during Vietnam, at least in the Marines.
