Humzah Mashkoor had just cleared security at Denver International Airport when the FBI showed up. The agents had come to arrest the 18-year-old, who is diagnosed with a developmental disability, and charge him with terror-related crimes. Mashkoor had gone to the airport ... as part of his alleged plot to join the Islamic State. The trip had been spurred by over a year of online exchanges starting when Mashkoor was 16 years old with four people he believed were members of ISIS. According to the Justice Department's criminal complaint, the four were actually undercover FBI agents. As a result of his conversations with the FBI, Mashkoor could face a lengthy sentence for attempting to provide material support to a terrorist organization. Law enforcement agents first became aware of Mashkoor's online activities in support of ISIS in November 2021. But instead of alerting his family ... FBI agents posing as ISIS members befriended him a year later and strung him along until he became a legal adult. Almost all of the conduct he is alleged to have committed took place when he was a juvenile. "This case appears consistent with a common fact pattern seen in tens, if not hundreds, of terrorism-related cases in which the FBI has effectively manufactured terrorist prosecutions," said Sahar Aziz, a national security expert. "If there was a serious terrorist threat in America, the FBI would not be spending its time entrapping a mentally ill minor."
