The OIG review did not find that the FBI had targeted any of the groups for investigation on the basis of their First Amendment activities. However, the OIG concluded that the factual basis for opening some of the
investigations of individuals affiliated with the groups was factually weak, and in several cases there was little indication of any possible federal crimes as opposed to state crimes. In some cases, the FBI
extended the duration of investigations involving advocacy groups or their members
without adequate basis, and in a few instances the
FBI improperly retained information about the groups in its files. The FBI also
classified some investigations relating to nonviolent civil disobedience under its “Acts of Terrorism” classification, which resulted in the watchlisting of subjects during the investigation.
In addition, in the course of our investigation, the OIG found that,
because of inaccurate information provided to FBI Director Robert Mueller regarding the circumstances of the FBI’s surveillance of an anti-war rally in Pittsburgh in 2002, the
Director unintentionally provided inaccurate testimony to Congress in May 2006. The Director, in reliance on the information provided to him by FBI personnel, testified that certain persons of interest in international terrorism matters were expected to be present at the rally, when in fact this was not the case.
The OIG’s specific findings relating to the individual advocacy groups are summarized below.
The OIG found numerous references to the Thomas Merton Center in documents describing investigative activities conducted by the FBI’s Pittsburgh Field Division. For example, in late November 2002, a probationary FBI agent in the Pittsburgh Field Division attended a public anti-war leafleting event sponsored by the Thomas Merton Center. The agent’s supervisor sent him to the rally on a slow work day (the day after Thanksgiving) and instructed him to look for Pittsburgh Field Division international terrorism subjects. The OIG found that the agent’s surveillance did not violate the Attorney General’s Guidelines.
However, in 2006, the FBI provided inaccurate information about the incident to the public and to Congress by claiming that the surveillance related to a particular person of interest in a terrorism investigation. This included
inaccurate testimony that FBI Director Robert Mueller provided to Congress in May 2006 in reliance on the information provided to him by FBI personnel. Contrary to the FBI’s statements, the OIG found no evidence that the FBI had any information at the time of the event that any terrorism subject would be present at the event. The OIG concluded that the erroneous statements to the public and Congress could have been
the result of extraordinary carelessness but were more likely the result of efforts by FBI personnel to justify the surveillance.

In summary, Mueller was incompetent and failed to notice the misconduct of his subordinates. But, he's competent now, and yet, again, failed to notice what his subordinates have been doing. Mind you, this is not an exclusive list of his failures and deceptions.
