I was unfortunate enough to see the US CNN report of the release of these guys. In general, the US TV coverage has been the typical sensationalist reporting one expects from a news "show".
There have been several interviews with US "experts" and the thrust has been along the lines of "US servicemen are highly trained..blah blah blah...would not have revealed ANY information or given "confessions"
Mind you - they also billed Jock Stirrup as a "British Royal Marines"
