As several people noted in comments, Obama's rationale for threatening to veto an anthrax investigation (investigations would undermine the State's credibility and thus dilute its authority) is very similar to the Catholic Church's explanation for why it concealed reports of so many abusive priests (disclosure would undermine the Church's credibility and thus dilute its authority). See, for instance, here, as well as here (Cardinal Christoph Schönborn: "the appearance of an infallible church was more important than anything else"). That was also the same rationale invoked by Justice Scalia when enjoining the Florida recount during the 2000 election (Scalia: a recount would "irreparably harm" Bush "by casting a cloud upon what he claims to be the legitimacy of his election"). Common to all of these suppression-justifying claims is the notion that preventing the truth from being examined and known is necessary to preserve institutional credibility and power.I wonder if Richard Dawkins will decide to make a citizen's arrest of Barack Obama? Or George Bush? The scale of the crimes involved in the case of US Presidents is far greater than even Popes.
