It's not "de facto" security policy; it's policy; file all the rest under "Deception and Denial"

From Washington Post today Pakistani military worried about collaborators

It is unclear how authentically committed Kayani and other top military leaders are to cleansing their ranks. U.S. officials and Pakistani analysts say support by the nation’s top military spy agency for insurgent groups, particularly those that attack in India and Afghanistan, is de facto security policy in Pakistan, not a matter of a few rogue elements.

But Kayani is under profound pressure, both from a domestic population fed up with the constant insurgent attacks and from a suspicious international community, which views the bin Laden hideout as the strongest evidence yet that Pakistan is playing a double game.

U.S. officials say they have no evidence that top Pakistani military or civilian leaders knew about bin Laden’s redoubt, though they are still examining intelligence gathered during the raid. Some say they doubt Kayani or Lt. Gen. Ahmad Shuja Pasha, head of the military’s Inter-Services Intelligence directorate, had direct knowledge; others find it hard to believe they did not, particularly because Kayani was head of the ISI in 2005, when bin Laden is believed to have taken refuge in Abbottabad.
