Would you have helped?? These people didnt

I was watching a show on tv, it was a caught on camera type show. There was a man who got onto a bus, and he had a 6 yr old kid with him (his son), he told his son to go sit down. He did. In the camera's sight there were about 4 or 5 people sitting on the bus, and there were probably more, but thats all the camera caught. So, the man with the kid, reaches into his bag and pulls out a hammer and starts beating a man that is asleeep in a chair. All of these people just get up and run out. Granted the man has a hammer and seems a little crazy, but Come on! All of those people couldve taken him down nd took his hammer....but did they? no! In fact as the man being beaten's cell phone dropped out of his pocket one of the men actually came back and took the phone!! Can you believe that?
