NEW YORK – As the U.S. ramps up efforts to root out homegrown terrorism, hundreds of people who have fallen under suspicion are in a state of limbo: Many say they have been singled out unfairly for scrutiny but have been neither charged nor cleared.
Some of them, mostly Muslims, have spent weeks in jail; others find it impossible to travel freely. Some say they have had their reputations destroyed by the news coverage. Many were questioned or tracked, and say they felt violated and fearful.
Lawsuits filed by suspects since 2006 have pried millions of dollars in settlements from the government. The U.S. Supreme Court this month heard one of the most serious challenges yet, the case of a Kansas man who claims his detention as a "material witness" destroyed his marriage and his career.
Many plaintiffs say they recognize the security challenges the government faces after Sept. 11; but in many cases, they complain, the government refuses to reveal why someone has attracted attention. Without that information, they argue, it is impossible to clear their names.
"It's a runaround," said Ayman Latif, an American who was stranded in Egypt for six months and questioned by U.S. agents last year after his name appeared on a no-fly list. "Maybe they had a hunch about something and my name came up and they were investigating it. But they wouldn't tell me what that hunch was."
The FBI says it needs secrecy to protect sensitive investigations and to avoid giving terrorists clues for avoiding detection.
The government does not disclose how many people it investigates, but an Associated Press analysis gives a glimpse of how the number has grown. Federal terrorism referrals — cases in which investigators have contacted prosecutors for guidance — have risen 44 percent since 2002, from 864 to 1,249 in 2010, according to the Transactional Records Access Clearinghouse, a research program at Syracuse University.
At the same time, the number of people on the FBI's consolidated terrorist watch list stands at 450,000, despite efforts since 2006 to winnow it down. Of those, 18,000 have been flagged for extra screening at airports. About 10,000 people are on the no-fly list, 500 to 1,000 of them U.S. citizens.
Some law enforcement experts say agents are simply doing their jobs by investigating leads, some of which pan out and some of which don't.
Moreover, police work is full of instances in which investigators know someone is up to no good, but they don't have enough evidence to make an arrest. Charles Strozier, director of the Center on Terrorism at New York's John Jay College of Criminal Justice, said the nature of counterterrorism work means investigators must monitor people for long periods even though they have committed no crime.
"Counterterrorism work completely reverses the familiar process of police work, which is, you have a crime, you collect forensic evidence and then you go after the bad guy," Strozier said. "In counterterrorism, everything must come before the crime is committed or you've completely failed at your task."
People who say they're caught in limbo include:
— Yasir Afifi, a 20-year-old college student in Santa Monica, Calif., who found a tracking device on his car when he went for an oil change in October. He said he believes he attracted attention because his father was a Muslim cleric, he sends money to Egypt to support his two younger brothers, and he travels to see them about once a year. The FBI would not comment on his case.
— Pascal Abidor, an Islamic studies Ph.D. student at McGill University in Montreal, who said he was frisked, taken off a train in handcuffs, put in a holding cell, fingerprinted and questioned after a border agent found on his laptop a picture of a militant rally he had downloaded for schoolwork. He has sued the Department of Homeland Security, saying the agent had no right to go through his computer without a warrant. In court papers, the government said agents do, in fact, have such a right. The government did not say what raised its suspicions.
— Abe Mashal, a 30-year-old dog trainer and former Marine from St. Charles, Ill., who was not allowed on a Chicago-to-Spokane flight in April because he had sent what he described as innocent e-mails to a Muslim cleric agents were watching. He said he refused to feed authorities information about fellow Muslims, and in June he joined 16 other people in a lawsuit challenging the way the FBI and Transportation Security Administration manage the terrorism watch list and no-fly list.
The Justice Department and Homeland Security would not comment on any evidence they may have against Mashal, but in their response to the lawsuit, government lawyers argued that keeping terrorists in the dark about investigators' techniques outweighs citizens' right to know why they have been put on blacklists. In October, Homeland Security sent Mashal a letter saying it had reviewed his file and "it has been determined that no changes or corrections are warranted at this time."
The House held hearings this month examining whether American Muslims are becoming "radicalized" to attack the United States. The government has warned that homegrown terrorism plots are on the rise and has redoubled efforts to root them out. Federal investigators note that "lone wolf" attacks such as in the 2009 Fort Hood shooting and the Times Square bombing attempt in May have put a new emphasis on finding radicals before they act.
"Beyond the sheer number of disruptions and arrests that have come to light, homegrown extremists are increasingly more savvy, harder to detect and able to connect with other extremists overseas," the Justice Department said in a statement to the AP.
But human rights groups say some of the government's favorite investigative tools are prone to abuse: warrantless surveillance, aggressive searches at the border, secretive watch lists, and laws that allow investigators to detain people as "material witnesses" — people they want to testify at a trial or before a grand jury. In other cases, investigators find immigration violations that allow them to hold suspects for months or years.
Authorities should have to explain to suspects why they are on the watch list and notify them if they have been cleared of wrongdoing, said Nusrat Choudhury, a lawyer for the American Civil Liberties Union who is representing people challenging the no-fly list.
"Instead, people are kind of left in the dark," Choudhury said.
In a statement, the FBI responded: "If the Terrorism Screening Center publicly revealed each person who was on the terrorist watch list, terrorist organizations would be able to circumvent the purpose of the terrorist watch list by determining in advance which of their members are likely to be questioned or detained."
This month, the U.S. Supreme Court heard arguments in the case of Abdullah Al-Kidd, a Kansas man arrested in 2003 as he tried to board a flight to Saudi Arabia to study Arabic and Islamic law. Al-Kidd was never charged with a crime, but prosecutors wanted him to testify against Sami Omar Al-Hussayen, a man charged with providing material support to terrorists. Like Al-Kidd, Al-Hussayen had attended the University of Idaho.
Al-Kidd was strip-searched repeatedly and held for 16 days in high-security cells, court documents show. For the next 15 months he was barred from traveling outside a four-state area and had to make weekly calls to a court officer and submit to a monthly search of his home. Al-Kidd said the stress destroyed his marriage and cost him his job delivering supplies to a store on Nellis Air Force Base in Nevada.
In the end, Al-Hussayen was acquitted of the terrorism charges but agreed to be deported for visa fraud. Al-Kidd was never called to testify in any trial. He has sued former Attorney General John Ashcroft, alleging he was deprived of his freedom.
The Justice Department says it uses its detention powers carefully and mainly in cases where it fears people will flee the country.
Sometimes the government simply gets the wrong suspect. Mistaken-arrest cases are becoming increasingly costly to taxpayers in the form of out-of-court settlements.
Since 2006, the government has paid $2 million to an Oregon man jailed after the 2004 train bombings in Madrid, $250,000 to a man detained after an aviation radio was found in his hotel room near New York's ground zero, and $1.8 million to seven men detained shortly after Sept. 11. Another lawsuit moving through a New York court represents 1,200 men rounded up after Sept. 11.
Law enforcement experts say such cases are a natural byproduct of aggressive detective work.
"Show me any kind of criminal or national security activity where you have no false positives or no false negatives," said James Carafano, a national security expert at the Heritage Foundation, a conservative Washington think tank. "If your metric of success is that no one's ever going to be inconvenienced, ever, then the system is never going to be good enough."
Other people have suffered from the publicity surrounding their arrests. Pakistani immigrant Pir Khan spent 76 days in solitary confinement last year after investigators detained him in the wake of the Times Square bombing attempt. Khan's nephew, who was living with him, had once sent money home to Pakistan using a money-transfer system common among Middle Eastern immigrants, in which payments are passed along until they reach an immigrant's family back home, according to investigators and Khan's own lawyer. Attempted bomber Faisal Shahzad was one link in the chain.
In jail, other inmates yelled, "Terrorist!" at him, Khan said. His American-born wife received death threats. Reporters interviewed his neighbors, scoured his wife's Facebook page for information and speculated on whether his marriage was a sham.
Khan said his credit rating was ruined after bills and other mail started disappearing, and he lost his taxi. No terrorism charges were ever brought against him. But now he is fighting deportation as an illegal immigrant. He is living in a Boston suburb and working as a mechanic.
"I lost a lot of things," Khan said. "I have to put it behind my back and just get on with my life."
Though Khan said he was questioned repeatedly about the bombings, the Justice Department said he was jailed solely because of immigration violations. Homeland Security said the decision to keep him in solitary was made by the sheriff's department in Plymouth County, Mass., which runs the jail. A sheriff's spokesman, John Birtwell, said only that detainees who have been in the news are sometimes separated to protect them from other prisoners.
Many suspects say they fear their names will forever carry a black mark.
Afifi, the California college student who found the tracking device on his car, said agents questioned him in front of his neighbors, hinted they knew about his new job and where he went on dates, and left him feeling frightened.
In November, Afifi went to Egypt to visit relatives. When he returned to the U.S., two federal agents were waiting for him at the airport. He was detained and questioned for four hours about his trip, he said. Last week he filed a lawsuit challenging FBI rules allowing agents to track suspects electronically without a warrant.
"I understand that maybe they have the right to do that to any American citizen as long as they think they have something against them," Afifi said. "But I don't know what they have against me, and that's the problem."
