EDIT: no guys, I'm pretty sure irritable old person is just code for asshole. Some old people are nice, you know.
Anyway I don't believe much of what Hersh alleges (except the parts we all already knew were true), but hopefully his source will surface or someone else will corroborate or not, etc.
A great interview with Hersh in the wake of his piece calling the official account of the assasination of Osama Bin Laden into account. A lot is beginning to be made of the pernicious and effective attacking of the messenger instead of the story by the press (in both instances). You can see it subtly in action here. He isn't an asshole, he just sees what they're doing and is beyond sick of it.
Nah, he's just an irritable old person (which he himself acknowledges) who has received a lot of personal attacks for his service and had been giving interviews all day when this guy spoke to him on the phone; and even if he were an asshole, that would be irrelevant to his worth as a journalist. But it's an interesting interview, so thanks for bringing it to people's attention.
