The U.S. government has prosecuted more than 800 people for terrorism since the 9/11 attacks. Most of them never committed an act of violence.

B oston Police Capt. Robert Ciccolo was one of the first responders to the Boston Marathon bombings. When his 23-year-old son, Alexander, who had converted to Islam and given himself the name Ali Al Amriki, began telling his father he was “not afraid to die for the cause,” Ciccolo became alarmed. Alexander had a history of mental illness, and his interest in Islam had become an obsession. In October 2014, Ciccolo contacted the FBI about his son. The federal agents could have monitored Alexander, or perhaps confronted him. Instead, as the bureau does in most such cases, agents launched an investigation. They found Alexander’s Facebook page, listed under his nom de guerre. There was a photograph of a young man in a wooded area wearing a head covering and holding a machete. “Another day in the forest strengthening myself,” the caption read. Another photo on his Facebook page appeared to show a dead American soldier. “Thank you Islamic State!” read the caption.

As part of a sting, an FBI informant contacted Alexander and offered to provide him with guns for an attack. After Alexander collected the weapons on July 4, 2015, FBI agents arrested him and charged him with terrorism-related offenses. As he was being processed at a detention center, he stabbed a nurse with a pen, causing a minor injury. His case made national news, and FBI Director James Comey told reporters that Alexander Ciccolo’s was among several plots related to the Fourth of July holiday that were foiled by counterterrorism agents. “I do believe that our work disrupted efforts to kill people, likely in connection with July 4,” Comey told reporters during a July 7, 2015, briefing. Alexander Ciccolo is among 63 men and women who have been arrested in FBI stings targeting ISIS sympathizers, according to an analysis of federal terrorism prosecutions by The Intercept. Demonstrating the evolving threat of terrorism in the United States, alleged ISIS sympathizers are now the primary targets of FBI stings, upstaging Al Qaeda, the Shabab, and all other terrorist groups. The first ISIS case in the United States culminated in an arrest in March 2014, and the number quickly grew. Fifty-eight people were charged in 2015 for alleged ISIS affiliations. In 2016, 32 FBI cases involved ISIS sympathizers, compared to just one each that year involving Al Qaeda and Shabab sympathizers. But as with earlier FBI stings that primarily targeted Al Qaeda sympathizers, most of the targets of the bureau’s ISIS stings are aspirational, not operational. In the majority of ISIS stings, targets were not in direct contact with ISIS representatives and did not have weapons of their own, government evidence showed. Instead, these targets were inspired by online propaganda to join ISIS and either made arrangements on their own to travel to Syria or were aided by FBI informants or undercover agents in their attempts join ISIS or plot attacks inside the United States.

After Alexander was arrested, FBI agents read him his Miranda rights. He then sat for an interview with FBI agents Paul Ambrogio and Julia Cowley. Dressed in a black T-shirt and jeans, he refused to talk about the guns, but he defended ISIS as a just organization, even as he demonstrated his ignorance about the group. The FBI recorded the interview. “ISIS claimed responsibility, right, for a lot of beheadings?” Ambrogio asked. “There’s someone who names himself Jihadi John and he beheads people, right? He does it in an online way so that people can see it. So what’s your feeling about that? They represent themselves as ISIS; they’re ISIS. What’s your feeling?” “The people that you see being executed are criminals,” Alexander answered. “They’re criminals. They’re the lowest of the low.” According to his family, Alexander, a high school dropout, had battled off and on with alcohol addiction. He was also admitted to a psychiatric institution when he was a teenager. As a child, he went back and forth between the homes of his father, a stern cop who did not respond to requests for comment for this story, and his mother, something of a free spirit. Alexander followed in his mother’s footsteps. “I raised him Catholic; he was baptized Catholic,” said Shelley MacInnes, his mother. “He stayed with his Catholic beliefs for quite a long time. I would say he is a very religious person and very spiritual, but as he got older, I think he started searching.” Alexander Ciccolo first gravitated toward Buddhism and spent time at the Grafton Peace Pagoda in Petersburgh, New York. In 2012, he and other members of the Peace Pagoda walked around Lake Ontario to raise awareness of the dangers of nuclear power. A photograph from the time shows him wearing a green V-neck T-shirt and holding a handwritten sign that reads: “Peace walk for no more Fukushima.” Shortly after, he returned to Massachusetts and announced that he would become a Muslim. “One day we were out having dinner, and he went to the bathroom,” MacInnes recalled. “He ran into an imam. … He was so excited. ‘Mom, you’re aren’t going to believe what just happened.’” Alexander became fixated on Islam and ISIS, and he would talk often with his parents about his newfound beliefs. “He’s always been an investigator, never takes anything at face value,” MacInnes said. “As far as ISIS goes, my personal opinion is that he was investigating the validity of that organization, rather than taking the media’s answer for it.” Following its sting playbook, the FBI introduced to Alexander an informant posing as an ISIS sympathizer. The informant and Alexander met for the first time in person on June 24, 2015. The young man told the informant that he wanted to travel to another state and use pressure cooker bombs to attack two bars and a police station. Over the course of a week, his plan changed from bombing bars and a police station to attacking a university. He boasted that he knew how to use sniper rifles and had grown up with guns. “I know what I’m doing,” he said. But Alexander didn’t have any weapons, aside from a couple of machetes. His only would-be bomb components were a pressure cooker purchased from Wal-Mart and some half-made Molotov cocktails. That’s where the FBI stepped in again. The undercover informant provided Alexander with two assault rifles and two handguns. As soon as Alexander took possession of the guns, FBI agents arrested him, charging him with attempting to provide material support to a terrorist organization and attempting to use weapons of mass destruction. He was also charged with being a felon in possession of firearms, owing to an earlier state conviction of driving under the influence.
