There was a shoot-out at a Miami night club a few days ago, several people were injured. A surveillance TV camera outside the building caught some of the action, and they rolled the video on the news tonight.
The CCTV video shows a group of patrons outside the club, milling about, smoking, talking, or just cooling off in the night air. Even though there is no audio, the moment the shooting begins is pretty obvious–the crowd on the sidewalk suddenly breaks into a run, all moving in the same direction. Some of the people look back as they run. One guy, who had been talking on his mobile phone, breaks away into a run, but the phone remains up to his ear and he continues the conversation as he sprints to safety.
