J-walking may seem like a relatively useless law to have but under certain circumstances an officer will still enforce it. What if someone runs across a busy high way or road with lots of traffic. This is a danger to everyone because not only could the person get hit. He could cause I car to swerve and hit another car and cause a wreck. (Schmalleger, 110) Apprehending offenders is another major responsibility that police have. Officers have the responsibility to arrest offenders of certain crimes during the crime if they see the law being broken and if not possible at that time, then after the crime is committed. (Schmalleger, 111) Lets say for example if a call is received reporting a suspicious person who is snooping around the side yard of a house. When the police officer arrives the man tries to walk out onto the side walk and start walking down the street like he was not doing anything. The officer flashes his/her lights and tells the man not to move. Upon frisking the suspect the officer finds a 9mm hand gun. It is his duty as a police officer to then apprehend the criminal for a concealed weapon. The above example could also be used for the next responsibility, that is preventing crime. By arresting the man with the hand gun the officer may have prevented another crime from
