A 22-year-old federal law that allows people to be held without charges if they have information about others' crimes is coming under fresh scrutiny in the courts, in Congress and within the Justice Department after reports that it has been abused in terrorism investigations.
The law allows so-called material witnesses to be held long enough to secure their testimony if there is reason to think they will flee. But lawyers for people detained as material witnesses say the law has been used to hold people who the government fears will commit terrorist acts in the future but whom it lacks probable cause to charge with a crime.
Concerns about how the law has been used have prompted calls from across the political spectrum for a reassessment. That debate has also ignited a broader one: whether the United States should join the several Western nations that have straightforward
preventive detention laws.

A department spokesman did not respond to requests for more current numbers. The department has for three years refused to give Congress fresher data on material witness detentions in terrorism investigations.
"They claim that they can't even tell us how many people they have detained" because of court sealing orders and grand jury secrecy rules, said Julie Katzman, a lawyer on Senator Leahy's staff.
