... wouldn't know that people (including military personnel) can do these things, ESPECIALLY when the 'leadership' harangues the world almost daily about the "evil-doers" and "terrorists." Just how many troops haven't heard that they're "hated because of their freedoms"?
When there's rot and corruption in the command structure, going all the way to the top, then these abuses (and worse) happen. This is part of the rotten moral sewage of war. I saw more than my share of morally corrupt officers - wannabe John Insane Waynes. One of the primary duties of the command structure is constantly policing itself and ensuring that abuses aren't encouraged and don't occur. With a 'volunteer' military, it can only be worse. (In fact, it's even worse with the civilians who gravitate to a war zone.) All too often, inciting a mob and rabble-rousing techniques are used as substitutes for 'leadership.'
