I'd hate to defend Bill O'Reilly but I think he may be telling the truth. My father is a good friend of Christopher Jones. They served in Vietnam together. After Vietnam Mr. Jones, iirc, got a law degree and, eventually, became a news reporter. He worked for the NY Fox station until retiring a couple of years ago. He was also stationed in Argentina during the Falkland wars. A couple of years ago he told me that he was kidnapped by the Argentine junta and tortured. They even did a mock execution. Why would they do this to a reporter? Because they thought he was CIA. So, if something like this was happening to a foreign reporter, one cannot imagine what was happening in the country as a whole. It was most likely a warzone even though the war was being fought hundreds of miles away.
Military dictatorships are like that all the time, particularly when in information control mode.
The Argentine Junta was particularly brutal-

None of which makes it a war zone for western journalists like O'Reilly any more than it was for journalists covering the Occupy Movement. Cops don't want them around & behave accordingly. They just had different ways of doing it in the Junta's Argentina. More of an "enhanced" form of interrogation/persuasion they studied in the School of the Americas. No western journalists died as a result of their ministrations, bet on that.
I love the bit about the British Journalists being expelled. I mean, no shit, Sherlock. Back in '42, had they crossed the channel into Axis territory they'd have been shot as spies.
O'Reilly? He's cultivated an image of a tough, smart & honest guy who just tells it the way he sees it, an opinionated asshole but a "very serious person" among Repub cognoscenti, somebody who carries the message well. For a price, of course, a handsome price.
If this flap knocks him down a peg, he earned it.
