There are many legal 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 are protected against unreasonable searches and seizures. Generally, the police may not search you or your home, or take things you own, without a warrant. A warrant is a paper that states, very exactly, the place to be searched and 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 good cause 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 policeman without a warrant to come into your home and he finds proof of a crime, the evidence may be used against you in court. If you do not want an officer to search you or your home and be does not has 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 must act reasonably and fairly at all times. They should use physical force only when it is needed to arrest someone or enforce a law.  Police may not use physical violence to teach someone a lesson.
   In all serious criminal cases you will get a lawyer free if you can not afford one. You should ask for a lawyer as soon as you are arrested and when you are first brought before a judge.
   No person can be forced to be a witness against himself. When in police custody, you do not have to answer questions that might help convict you of a crime. This means you may remain silent. You also may refuse to answer questions unless a lawyer is present. If you give information about a crime or confess to a crime because you were forced to do so, the information or statements cannot be used against you in court.
