The mission of the FBI section that operates the National Instant Criminal Background Check System (NICS Section) is to ensure national security and public safety by providing the accurate and timely determination of a person’s eligibility to possess firearms and explosives in accordance with federal law. Under the Brady Handgun Violence Prevention Act and implementing regulations, the FBI and designated state and local criminal justice agencies use NICS to conduct checks on individuals before federal firearms licensees (gun dealers) may transfer any firearm to an unlicensed individual. Also, pursuant to the Safe Explosives Act, in general, any person seeking to (1) engage in the business of importing, manufacturing, or dealing in explosive materials or (2) transport, ship, cause to be transported, or receive explosive materials must obtain a federal license or permit, respectively, issued by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). To assist ATF, in February 2003, the FBI began conducting NICS background checks on individuals seeking to obtain a federal explosives license or permit. Persons prohibited by federal law from possessing firearms or explosives include convicted felons, fugitives, unlawful controlled-substance users and persons addicted to a controlled substance, and aliens (any individual not a citizen or national of the United States) who are illegally or unlawfully in the United States, among others. One of the databases that NICS searches is the FBI’s National Crime Information Center (NCIC) database, which contains criminal justice information (e.g., names of persons who have outstanding warrants) and also includes applicable records from the Terrorist Screening Center’s (TSC) consolidated terrorist screening database. In general, individuals who are reasonably suspected of having possible links to terrorism—in addition to individuals with known links—are to be nominated for inclusion on the consolidated terrorist watchlist by the FBI and other members of the intelligence community. One of the stated policy objectives of the government’s consolidated watchlist is the coordinated collection of information for use in investigations and threat analyses. Terrorist watchlist records in the NCIC database are maintained in the Known or Suspected Terrorist File (formerly the Violent Gang and Terrorist Organization File), which was designed to provide law enforcement personnel with the means to exchange information on known or suspected terrorists. In May 2009, we reported that from February 2004 through February 2009, a total of 963 NICS background checks resulted in valid matches with individuals on the terrorist watchlist. Of these transactions, approximately 90 percent (865 of 963) were allowed to proceed because the checks revealed no prohibiting information, such as felony convictions, illegal immigrant status, or other disqualifying factors. Two of the 865 transactions that were allowed to proceed involved explosives background checks. The FBI does not know how often a firearm was actually transferred or if a firearm or explosives license or permit was granted, because gun dealers and explosives dealers are required to maintain but not report this information to the NICS Section. About 10 percent (98 of 963) of the transactions were denied based on the existence of prohibiting information. No transactions involving explosives background checks were denied. For today’s hearing, we obtained updated statistics from the FBI through February 2010. Specifically, from March 2009 through February 2010, FBI data show that 272 NICS background checks resulted in valid matches with individuals on the terrorist watchlist. One of the 272 transactions involved an explosives background check, which was allowed to proceed because the check revealed no disqualifying factors under the Safe Explosives Act. According to FBI officials, several of the 272 background checks resulted in matches to watchlist records that—in addition to being in the FBI’s Known or Suspected Terrorist File—were on the Transportation Security Administration’s “No Fly” list. In general, persons on the No Fly list are deemed to be a threat to civil aviation or national security and therefore should be precluded from boarding an aircraft. According to FBI officials, all of these transactions were allowed to proceed because the background checks revealed no prohibiting information under current law. In total, individuals on the terrorist watchlist have been involved in firearm and explosives background checks 1,228 times since NICS started conducting these checks in February 2004, of which 1,119 (about 91 percent) of the transactions were allowed to proceed while 109 were denied, as shown in table 1. According to the FBI, the 1,228 NICS transactions with valid matches against the terrorist watchlist involved about 650 unique individuals, of which about 450 were involved in multiple transactions and 6 were involved in 10 or more transactions. Based on our previous work, the NICS Section started to catalog the reasons why NICS transactions involving individuals on the terrorist watchlist were denied. According to the NICS Section, from April 2009 through February 2010, the reasons for denials included felony conviction, illegal alien status, under indictment, fugitive from justice, and mental defective. In October 2007, we reported that screening agencies generally do not check against all records in TSC’s consolidated terrorist watchlist because screening against certain records (1) may not be needed to support the respective agency’s mission, (2) may not be possible due to the requirements of computer programs used to check individuals against watchlist records, or (3) may not be operationally feasible. Rather, each day, TSC exports applicable records from the consolidated watchlist to federal government databases that agencies use to screen individuals for mission-related concerns. We raised questions about the extent to which not screening against TSC’s entire consolidated watchlist during NICS background checks posed a security vulnerability. According to TSC officials, not all records in the consolidated watchlist are used during NICS background checks. The officials explained that in order for terrorist information to be exported to NCIC’s Known or Suspected Terrorist File, the biographic information associated with a record must contain sufficient identifying data so that a person being screened can be matched to or disassociated from an individual on the watchlist. The officials noted that since not all records in TSC’s consolidated watchlist contain this level of biographic information required for this type of screening, not all records from the watchlist can be used for NICS background checks. According to TSC officials, the majority of records that do not contain sufficient identifying data are related to foreign nationals who would not be prospective purchasers of firearms or explosives within the United States and therefore would not be subject to NICS checks. We are continuing to review this issue as part of our ongoing review of the terrorist watchlist. The FBI has taken additional actions to use information obtained from NICS background checks to support investigations and other counterterrorism activities. These actions include providing guidance to FBI case agents on how to obtain information related to NICS checks and efforts to analyze and share information on individuals matched to the terrorist watchlist. The FBI has provided guidance to its case agents on how to obtain information on individuals matched to the terrorist watchlist during NICS background checks. According to FBI Counterterrorism Division officials, TSC notifies the division when a NICS background check is matched to an individual on the terrorist watchlist. After verifying the accuracy of the match, the Counterterrorism Division will advise the FBI case agent that the individual attempted to purchase a firearm or obtain a firearm or explosives license or permit. The division will also provide the agent with contact information for the NICS Section and advise the agent to contact the section to answer additional questions. According to Counterterrorism Division officials, the case agent is also advised to contact ATF to obtain a copy of the form the individual used to initiate the transaction. For verified matches, NICS Section personnel are to determine if FBI case agents have information that may disqualify the individual from possessing a firearm or explosives—such as information that has been recently acquired but not yet available in the automated databases searched by NICS. To assist the division in searching for prohibiting information, NICS Section personnel are to share all available information that is captured in the NICS database with the case agent—name, date of birth, place of birth, height, weight, sex, race, country of citizenship, alien or admission number, type of firearm involved in the check (handgun, long gun, or other), and any exceptions to disqualifying factors claimed by an alien. According to FBI officials, these procedures have been successful in enabling the NICS Section to deny several gun transactions involving individuals on the terrorist watchlist based on disqualifying factors under current law. The FBI did not maintain specific data on the number of such denials. In response to a recommendation made in our January 2005 report, FBI headquarters provided guidance to its field offices in April 2005 on the types of additional information available to a field office and the process for obtaining that information if a known or suspected terrorist attempts to obtain a firearm from a gun dealer or a firearm or explosives license or permit. Regarding gun purchases, the guidance notes that if requested by an FBI field office, NICS personnel have been instructed to contact the gun dealer to obtain additional information about the prospective purchaser—such as the purchaser’s residence address and the government-issued photo identification used by the purchaser (e.g., drivers license)—and the transaction, including the make, model, and serial number of any firearm purchased. According to the guidance, gun dealers are not legally obligated under either NICS or ATF regulations to provide this additional information to NICS personnel. If the gun dealer refuses, the guidance notes that FBI field offices are encouraged to coordinate with ATF to obtain this information. ATF can obtain a copy of the form individuals must fill out to purchase firearms (ATF Form 4473), which contains additional information that may be useful to FBI counterterrorism officials. Regarding a firearm or explosives permit, the FBI’s April 2005 guidance also addresses state permits that are approved by ATF as alternative permits that can be used to purchase firearms. Specifically, if requested by an FBI field office, NICS personnel have been instructed to contact the gun dealer to obtain all information from the permit application.
