Counterterrorism officials in FBI headquarters slowed an investigation into a possible conspirator in the 2005 London bombings by forcing a field agent to return documents acquired from a U.S. university. Why? Because the agent received the documents through a lawful subpoena, while headquarters wanted him to demand the records under the USA Patriot Act, using a power the FBI did not have, but desperately wanted.
