US court dismisses smuggling case against Russian scientist Ksenia Petrova A federal district judge dismissed all charges against Harvard University researcher Ksenia Petrova without a hearing, AP reports. Earlier today, the US Department of Justice asked to dismiss Petrova's case. The Department believes that further disputes over evidence disclosure and litigation "will divert significant time and attention from more substantive federal interests." "At this point, spending the resources to continue this criminal prosecution exceeds the public interest to resolve it," the department said.
