 FACT: In the opening line, a tour guide tells the people on the tour  boat that Alcatrazs inmates have included "Al Capone, Baby Face  Nelson, and Machine Gun Kelly." In fact, Baby Face Nelson (aka  Lester Gillis) was never incarcerated at Alcatraz. He was killed in  a gunfight with FBI agents in 1934, the same year Alcatraz opened as  a prison.
