In VICE's latest installment of 'I Was There', photojournalist Lou Dematteis recounts photographing the capture of U.S. mercenary Eugene Hasenfus after his cargo plane was shot down in the Nicaraguan countryside. Lou's photograph, along with reporting from his colleagues on the ground, exposed how the American government, including the CIA, was illegally using funds made from selling arms to Iran to secretly fund the Contra rebels in Nicaragua. This became known as the Iran-Contra affair and the resulting scandal led to the conviction and resignation of several Reagan Administration officials, most notably Lieutenant Colonel Oliver North.
