The story here is not that Pakistan knew about OBL's whereabouts (which has been known for a while), but that Hersh is reporting that Pakistan had OBL under house arrest and allowed the United States to kill him, with both government's covering this all up as a "daring nighttime raid."

NBC's more limited story seems to have better sourcing. Hersh's reporting on this is problematic:
