Chessani should have acted before, immediately upon notificaiton and realization, that a problem existed. His atty is now performing a BS act to a public audience for sympathy. BS that has nothing to do with the incident whatsoever. There was nothing in the ROE that were a problem here. As far as Wuterich and those involved in the shooting goes, they shot up at least 2 houses and killed 15 noncombatants. Tossing the grenades in the window was fine, but the entry team shot those people at close range, no return fire, or weapons present, and they were mostly women and children. To top that off, SSgt Wuterich filed a false field report regarding the incident, saying they were killed by the IED, that killed Lance Cpl Terrezas.
It should have all been straightened out by Lt Col Chessani and those involved immediately. That is his duty. Ignoring what appears to be unlawful action is not.
I'll continue to give these the Marines the presumption of innocence. I'd do the same if your son or daughter was involved.
