Naive students are not the only researchers to run afoul of new federal interest in the handling of toxic materials. In January, prominent infectious-disease researcher Thomas Butler, of Texas Tech University Health Sciences Center, ended up in handcuffs after he was alleged to have falsely reported several vials of plague bacteria as missing. According to the journal Science and other publications, Butler admitted he made the false report to cover up the fact that he had forgotten to properly document destroying the bacteria, as required by the new rules. Released on bond, he was made to give up his passport, agree to stay entirely away from biological research materials, and wear an electronic monitor, pending trial. Butler was asking for trouble, clearly, but a colleague at his university described the incident as "a minor problem that's been handled with a wartime mentality."
