Suicidal man pushed off the bridge

A man who had held up traffic on a bridge in Beijing was pushed today. Chen Fuchao was up to his yen in debt and thought he might end it all by jumping off a bridge. The Police cordoned off the area, set up an inflatable catchy thingy and then waited. After several hours Lai Jiansheng, a passerby, asked to try and talk the man down, but he was turned down. So he went up to the bridge and snuck through the blockade. He walked right up to Chen, shook his hand and then shoved him off. Chen landed in the partially inflated emergency catchy thing while Lai smiled and saluted as he fell. Chen injured his elbow and his spine. Lai was arrested. I just think this is funny, it's like Lethal Weapon for real. Now, Lai has some sort of mental disorder, but I have to say he was right on the money here. There was something to catch the guy. The guy had held up traffic for five hours. Lai thought Chen was being selfish. Seems about right to me. And trust me it is selfish, I can speak with authority on that. So I just think that all's well that ends well. No one died. I doubt Chen will try to off himself again. Traffic was restored to normal. And the police could go about doing something more useful. Why go about arresting Lai? Does this mean I am twisted? IF it does then oh freakin' well.
