“The U.S. acted like a criminal thug,” the report said.

For all its untempered language and institutional constraints, the report offered the most comprehensive official account yet of Bin Laden’s time on the run in Pakistan and the American Navy SEALs raid that took his life.

The four-member commission was comprised of Justice Javed Iqbal of the Supreme Court, a retired police officer, a retired diplomat and a retired army general. It first met in July 2011, two months after the American raid, and has held 52 hearings and conducted seven field visits.

American officials did not cooperate with the commission, and on Monday, Jen Psaki, a State Department spokeswoman, declined to comment on the report. One senior American official who follows Pakistan said he had not yet read a copy of the commission’s voluminous report, but he said that from summaries he had seen, the document appeared to offer “the Pakistan people some accounting of how Bin Laden came to end up where he did.”

In many places, the Pakistani report seems to seethe with frustration at the failures of Pakistani officials to find Bin Laden before the Americans could get to him.

It highlighted inept border officials who allowed one of his wives to pass into Iran, inept municipal officials who failed to spot the unusual construction at his house, intelligence officials who hoarded information, and senior police officials who it deemed guilty of a “grave dereliction of duty.”

The commission interviewed military officials who failed to detect American aircraft entering Pakistani airspace, and it noted that on the night of May 2, the first Pakistani fighter jets were scrambled 24 minutes after the Americans had left Pakistan with Bin Laden’s body on board.

“The extent of incompetence, to put it mildly, was astounding, if not unbelievable,” the report said.
