When arresting someone, police officers typically say a set of phrases that inform the person of their rights and the reason for their arrest. The specific words used may vary depending on the jurisdiction, the circumstances of the arrest, and the officers training and experience. However, the following phrases are commonly used:

• "You are under arrest" or "I am placing you under arrest": This is a formal statement that indicates that the person is being taken into custody.

• "You have the right to remain silent" or "You have the right to remain silent and refuse to answer questions": This statement advises the person of their Miranda rights, which include the right to remain silent and the right to an attorney.

• "Anything you say can and will be used against you in a court of law": This is a warning that anything the person says during the arrest or questioning can be used as evidence.

• "You have the right to an attorney" or "If you cannot afford an attorney, one will be provided for you": This is a statement that advises the person of their right to an attorney and informs them that an attorney will be appointed for them if they cannot afford one.

After the arrest, the officer must read the Miranda warning to the suspect, which informs them of their rights regarding police questioning. The warning says: "You have the right to remain silent. Anything you say can and will be used against you in a court of law. You have the right to an attorney. If you cannot afford an attorney, one will be provided for you. Do you understand the rights I have just read to you?". It is important to note that Miranda rights do not go into effect until after an arrest is made.
