"The F.B.I. tried to recruit an Iranian scientist as an informant. When he balked, the payback was brutal." Laura Secor tells the story of Sirous Asgari, an Iranian who had once attended graduate school in America, where his wife gave birth to his American citizen daughter, and where his two sons attended American universities. But on a visit in 2017 he was detained by the F.B.I. He was charged with "theft of trade secrets, visa fraud, and eleven counts of wire fraud." He considered the charges to be nonsense and refused a deal offered that appeared to be the real reason behind the charges — to get him to agree to act as an informant, that is to spy for the US back in Iran. He fought the trumped up charges in an American courtroom and won. But after the judge dismissed all charges against him, even before he could leave the courtroom, he was detained by I.C.E. And then the real hell began.
