Answer:
Officer must inform people of their rights before questioning them in custody.
Step-by-step explanation:
The fifth amendment guarantees the US citizens specific rights that includes not to testify against yourself if you are accused of a crime. It was part of Bill of Rights. It was added to the Constitution to protect citizens rights and freedoms. They didn't want the government to encroach upon the peoples rights. it makes it harder for the government to convict us of crimes,take our freedom or property. It says that our life property and liberty cannot be taken away without due process of law. It was in United States v. Hubbell that no person can be compelled in criminal case to be a witness against himself.
