Here's an article about Watergate and the new claim by Jeb Magruder that he overheard Nixon authorize the infamous break-in. As I said earlier, I'm skeptical about Magruder's delayed-action admission but I do think that it's highly likely Nixon okayed the plan, either in the abstract or the specific.
One of the things that always makes me suspicious about alleged public fibs is misplaced outrage. O.J. Simpson never went on TV and screamed, "I'm going to get the dirty bastard who murdered my ex-wife and her friend!" He never even got too upset that, to hear him tell it, the L.A.P.D. had engaged in a massive conspiracy to frame him for that crime. He was more upset over minor affronts to his image.
In presidential scandals, chief execs claim to have been misled or circumvented by their underlings but they never seem to get angry with those underlings. Misleading statements that turn up in George W. Bush's speeches seem to be everyone's fault but his, but we don't see him chastising the parties responsible, let alone firing them. Nixon never pounded the desk and declared, "Breaking into the Watergate Hotel was a criminal act and I'm going to get to the bottom of this and throw the responsible parties in prison." Instead, he said some of them might be "overzealous."
The article linked above is right: We may never know to what extent if any Nixon authorized the break-in. But he sure acted like he had.
