Police officers protect you and your family, and your friends. They keep us safe from people who don't want to follow the law. To be a police officer, you must pass a lot of physical and written exams. Police officers have to be in good shape in order to chase criminals. They also must have a good knowledge of the legal system and they have to participate in criminal cases that go to court. They are often expected to appear in court to describe certain details of crimes.
Above all, police are there to help people in need. So if you are lost or ever need help- find a police officer!!
