This is what I've been told in during SERE classes. I've not personally interviewed them, and I wasn't there, so I can't vouch for the information personally. As with anything else the Army tells me, I go with the information as far as it sounds reasonable. Where I work, being a POW is a occupational hazard that is taken pretty seriously. I try not to blow off information that could be relevant.
Also, I don't know who James Webb is or why he wasn't notified that POWs are in danger of being abused, or what bearing that has on the discussion.
