From the article:
"Consider what happened when another Puerto Rican group detonated a small bomb in a Bronx cinema while a rapt crowd watched a movie called The Liberation of L.B. Jones. When police ordered everyone to leave, an NYPD spokesman complained, the audience angry refused, demanding to see the rest of the movie. When police insisted, “They about tore the place apart.”"
Think about that: A bomb goes off in the very theater you're in and instead of running or leaving when police tell you it's time to go, you get mad and wanna continue watching the flick.
