Is this an authentic government website?

“In the weeks following the raid on Osama bin Laden’s compound in Abbottabad, Pakistan by United States forces, U.S. Intelligence Community analysts sifted through the recovered digital and hard copy materials in search of clues that would reveal ongoing al-Qa`ida plots, identities and locations of al-Qa`ida personnel, and other information of immediate importance.

On May 20, 2015, the ODNI released a sizeable tranche of documents recovered from the compound used to hide Osama bin Laden. March 1, 2016, marks the release of the second tranche of material gleaned from the Abbottabad raid. These releases, which followed a rigorous interagency review, align with the President’s call for increased transparency–consistent with national security prerogatives–and the 2014 Intelligence Authorization Act, which required the ODNI to conduct a review of the documents for release.”

It contains “writings” from Bin Laden, that if real, paint a completely different picture from what we are being told, and raises the question of whether anyone in government even reads this stuff.
