Guns bought legally in spite of being flagged by FBI
In spite of being on the FBI’s radar, Omar Mateen was permitted to buy guns.
Law enforcement sources confirmed that Mateen was on the FBI’s radar but not necessarily on a watch list. But even appearing on the list wouldn’t have necessarily prevented him from obtaining weapons. “Being on the watch list is not in itself disqualifying, under law. The disqualifying elements of the investigation may be classified,” ABC News consultant and former acting Homeland Security undersecretary John Cohen said.
