Visitors to the cinema in the Denver suburbs were completely shocked by the shooting during the new Batman film 'The Dark Knight Rises'. Another eyewitness told a reporter that the perpetrator threw two cans of gas into the hall. “At first no one responded because we thought it was a stunt that was part of the film.” According to this eyewitness, the man first shot into the air and then towards people. "He didn't seem to have a specific target. He shot at random."
