If David Petraeus was still running the CIA, he might call for some "enhanced interrogation techniques" to be used on a buddy who thought it would be funny to mail a fake grenade to the general's New York City office. The package was opened by the general's secretary, who thought it was real and called police, causing the evacuation of the office and the closure of part of 58th Street, reports NY1. It's not clear whether Petraeus was in his office at the time. (More David Petraeus stories.)
