The Department of Justice's Inspector General, Michael Horowitz, last week released a new report detailing at least six terrorist attacks on American soil that the FBI could have prevented between November 2009 and January 2017 under former FBI Director James Comey's supervision.

According to Horowitz, the FBI was made aware of six homegrown violent extremists (HVE), but because of the agency's rush to close terrorism cases, threats were not adequately assessed and vetted. 

The FBI established the HVE policy after the September 11th attacks to prevent future terrorist threats.

Following these attacks, the FBI conducted reviews and determined there were weaknesses in its HVE assessment processes. However, we found that the FBI has not taken sufficient action to address these weaknesses. Additionally, in 2017, the FBI conducted an enterprise-wide review and identified potential terrorist threats that may not have been adequately assessed during calendar years (CY) 2014 through 2016, which amounted to 6 percent of the total assessments reviewed. We found that the FBI did not take adequate action on nearly 40 percent of these assessments for 18 months. After we inquired about the lack of action, the FBI reexamined these assessments and, in some instances, the reexamination resulted in the opening of an investigation. We further found that the FBI has experienced a substantial influx of reports of suspicious incidents, but has not developed comprehensive strategies for addressing the challenges associated with the potential cross-over between terrorist threats and other categories of threats, for example, those posed by individuals with mental health issues and criminal threats to life.

Specifically, the FBI had information on the following incidents:

The report highlighted issues in how the FBI failed to handle information. One of the recommendations Horowitz made was for the FBI to develop "formal policies on the assignment and completion of routine counterterrorism assessments to address issues of timeliness and to encourage prioritization of counterterrorism assessments. In addition, this review identified concerns about the assignment of Task Force Officers as the lead investigators on certain assessments and investigations, and the need for increased training for counterterrorism Task Force Officers."

According to the report, FBI agents were quick to close terrorism cases. Those quick closures meant the FBI failed to assess potential threats adequately. 

Since September 11, 2001, HVEs have carried out over 20 attacks in the United States, some of which occurred after the FBI closed a counterterrorism investigation or assessment on the individual. Following these attacks, the FBI conducted reviews and determined there were weaknesses in its HVE assessment processes.

However, we found that the FBI has not taken sufficient action to address these weaknesses.

Additionally, in 2017, the FBI conducted an enterprise-wide review and identified potential terrorist threats that may not have been adequately assessed during calendar years (CY) 2014 through 2016, which amounted to 6 percent of the total assessments reviewed. We found that the FBI did not take adequate action on nearly 40 percent of these assessments for 18 months. After we inquired about the lack of action, the FBI reexamined these assessments and, in some instances, the reexamination resulted in the opening of an investigation.

Sen. Rand Paul (R-KY) slammed former FBI Director James Comey's leadership for not taking responsibility for the agency's failure to protect innocent Americans, specifically those who were at Pulse Night Club.
