Mitnick served five years in prison—four-and-a-half years' pre-trial and eight months in solitary confinement—because, according to Mitnick, law enforcement officials convinced a judge that he had the ability to "start a nuclear war by whistling into a pay phone", implying that law enforcement told the judge that he could somehow dial into the NORAD modem via a payphone from prison and communicate with the modem by whistling to launch nuclear missiles.
