DETROIT — A federal judge on Monday ordered that nine members of an extremist militia accused of plotting to kill police officers be freed on bond until their trial, saying that prosecutors did not demonstrate that the defendants would pose a danger if released.

The judge, Victoria A. Roberts of Federal District Court, said the defendants would be subject to home detention, electronic monitoring and curfews. Judge Roberts said they were not allowed to have access to weapons or have contact with one another unless their lawyers were present.

“They were talking about killing police officers,” Leslie Larsen, the Federal Bureau of Investigation agent in charge of the Hutaree investigation, testified. “I don’t think you can joke around about that.”

Judge Roberts and the defendants’ lawyers expressed frustration that Ms. Larsen was unable to answer most questions she was asked, generally saying that she needed to review her notes or that she had not read many of the reports her colleagues had prepared about the group.

Ronald W. Waterstreet, an assistant United States attorney, told the judge that about 25 Hutaree members had not been indicted and could potentially help the defendants flee if they were released. But Judge Roberts cited the other members who had not been charged with any crimes as reason to believe “the offenses charged against these defendants may not be as serious as the government contends.”
