Oh, I see. The CG's only sanctioned role is to engage the WPPA and dump the charges, whatever they may be, whatever the evidence gathered is.
What the honorable Congressman is saying is that LTCOL West has done nothing to violate their laws that would warrant a court martial and he should be left alone.
Wow. I didn't realize that being a congresscritter made one omniscient. No need for any sort of hearing. Heck, let's get rid of the JAG. No need to investigate anything ever again, we'll ask a congresscritter what happened, and he'll come to the correct conclusion based solely on heavily-spun editorializing masquerading as "reporting."
That is your recommendation, not mine. The problem is that you are seeking a judicial solution to what is fundamentally a political problem. Decisions about rules of engagement, treatment of captured enemy agents, etc. are fundamentally political decisions. War is, after all, the continuation of politics by other means. War and its conduct is not judicial, it is political. The military would like to leave it to a mindless process and say that the process is working so no one has to gage where they are on the political correctness meter. Congress just told them hey, this really is political, make your decision like a man and like the commissioned officer we said you are and stand up and be counted.
As Sun Tzu reminds us, waging war is an issue of state. Congress knows that this discussion is about fundamental policy. You in your small-minded ignorance want to treat it like a parking ticket.
