WHAT WOULD YOU DO?

There's a television program entitled, "What Would You Do." For those of you who haven't seen it, actors create a situation in a public area while the cameras roll. It's a test to see who will get involved, and why, when they see something wrong.
     Mike had his own test recently, though it wasn't filmed. Here's how it went:
     He took the Front Runner (the Wasatch Front commuter train) from Ogden to Salt Lake, then transferred to the light rail train (Trax) in Salt Lake to travel to Murray. My sister Bonnie and her daughter Cathy were with me and our plan was to meet Mike at the 4500 South stop. We waited, but no Mike. We wondered if he missed his connection and would be on the next train, so we waited longer. Soon I received a call from Mike, who was at the 5100 South stop.
     Trax was crowded when it left Salt Lake and Mike, who had gotten on early, gave up his seat to a woman. As Mike never meets a stranger, he stood nearby and visited with the woman, until their conversation was interrupted by an obscene outburst. All eyes were turned toward a man lying on the floor in the junction between two cars. A man, who appeared to be high or crazy--or both, screamed every vulgar epithet possible. People became upset, children displayed frightened faces and a couple of women cried.  A group of men circling the wild man seemed to be egging him on, including a 6'5" giant, whose appearance perhaps deterred thoughts of intervening by all except Mike. He approached the group and in a firm voice told Wild Man to knock it off.
     "Yes, sir. Yes, sir," said Wild Man, and he did--until Mike returned to his place. Then, with further encouragement from his cheering squad, Wild Man became even more belligerent and violent, all still while lying on the floor. Mike returned to him, grabbed him by the top of his hood and drug Wild Man toward an exit.  When the train stopped, Mike tried to get Wild Man in position, and asked other to open the door, but the train was already in motion again. Mike called and alerted UTA (Utah Transit Authority) of the situation. By the next stop, people hopped to get the doors open and to the applause and cheers of the passengers, Mike drug Wild Man off the train and thrust him into the arms of the waiting officers.
     Mike may not have been the oldest passenger on the train, but there were certainly others much more physically capable than he. Why didn't they react?  Why is it easier to turn a blind eye than to get involved? I hope if I ever get into a situation where I need help, Mike--or someone like him, is nearby.
