A Harvard sophomore didn't want to take his finals exams yesterday, so he shut down the school by emailing bomb threats to Harvard police.

Half-an-hour before his scheduled exam, 20-year-old psychology major Eldo Kim sent out an email claiming that there were two shrapnel bombs on campus. He listed four possible on-campus locations — including, of course, the building his exam was scheduled in.

It took about 20 minutes for the school to alert students, around the same time they began evacuating the named buildings. President Obama was briefed. Kim's final was canceled.

At the same time, the FBI — in coordination with the Bureau of Alcohol, Tobacco, Firearms, and Explosives; the United States Secret Service; the Harvard University Police Department; the Cambridge Police Department; the Boston Police Department; and the Massachusetts State Police — responded to Harvard Yard.

He must have only gotten an A- in campus terrorism, because despite evasive tactics that included the anonymous email service Guerrilla Mail and using TOR to hide his IP address, Kim was confessing to an FBI agent by nightfall.

He told the agent he chose the word “shrapnel” because "it sounded more dangerous."

He's facing five years in prison, but hey, no finals.
