Which duty upon detention involves informing the person of their rights?

The correct choice involves advising the person of their right to remain silent, which is an essential component of ensuring that individuals understand their rights during a detention. This practice stems from the Miranda rights established by the U.S. Supreme Court in the Miranda v. Arizona case. When an individual is detained by law enforcement, they must be informed of their right to remain silent and that anything they say can be used against them in court. This notification is crucial in protecting an individual’s Fifth Amendment rights against self-incrimination and ensuring they are aware of their legal protections.

The requirement to inform individuals of their right to remain silent allows them to make an informed decision about whether or not to speak to law enforcement, thus safeguarding their rights during the criminal justice process.
