There are many rights to make sure that people will be treated fairly when they are suspected or accused of a crime. Sometimes these rights are called "due process of law". In using these rights, a person should have the help of a lawyer. You have a right to protect against unreasonable searches and seizures. The police generally may not search you or your home, or take things you own, without a "warrant". A warrant is a paper which states, very exactly, the place to be searched and the things to be taken. Sometimes, however, the police will not need a warrant to search you or your property. If an officer sees you committing a crime, or if he has a good reason to believe you have committed a serious crime, he may arrest you and search you and the area right around you without a warrant. If you invite a police without a warrant to come into your house and he finds proof of crime, the evidence may be used against you in court. If you do not want an officer to search you or your home and he does not have a warrant, tell him that you do not give him the right to search. However, if the officer will not listen, do not try to stop him. It is dangerous to resist and it may be illegal to do so. Any evidence which a policeman gets during an unlawful search and seizure cannot be used against you. Police officers must act reasonably and fairly at all times. They should use physical force only when it is needed to arrest someone to enforce a law. They may not use physical violence to "teach someone a lesson". The police can use physical force only when   _  . A) they want to teach the habitual thief a lesson B) the criminal resists arrest C) they catch the criminal on the spot D) the suspect talks back
