a witness of a theft incident
　　Yesterday I witnessed a theft incident on my way home.The thelf was so that it left me a very deep impression...It was in the rush hour when many people would buy tickets the subway station.A woman took her purse out and pay for the ticket and then she put her purse back into her bag and turn to leave when a middle aged man rushed pass her muttering:"excuse me ", she didn't feel unusual and went into station indeed her purse had been stolen by that man. To our surprise the thelf seems not to be nervous at all and even began to look others up and down. Maybe he was searching for the next target.At that time,some persons including me witnessed the process but unfortunately no one dared to warn that woman.
　　This incident makes me ashamed and leave me a deep thought:the pickpocket has posed a great threat to residents and visitors' property safety. Undoutedly, it is a urgent thing to take action to prevent pickpocket .However, it cannot dependent on the police only ,instead it needs our common efforts .We connot shut our eyes and mouths to the pickpocket anymore .It should be kept in our minds that our forces are far beyond these thelves.
