 FAKE: When Chief Slater dials the terrorists, he uses a cell phone  to call into the school. When the terrorist is making his demands,  he is speaking not only to the chief, but to two FBI agents at the  same time, all on individual cell phones. It is impossible to  conference call three different cell phones at once, unless the  Chief dialed one FBI agent, that agent dialed the other FBI agent,  and the last agent dialed into the school.
