Why is a person being arrested given the right to remain silent?

To avoid self-incrimination
To prepare their statement
To decide what to tell their lawyer
To protect them from abuse by the police

The right to remain silent when being arrested is a fundamental right protected by the Fifth Amendment of the United States Constitution. It was established to protect individuals from self-incrimination, which means that they cannot be compelled to provide evidence against themselves. This right is a cornerstone of the US legal system and ensures that individuals are not forced to testify against themselves, especially when being questioned by law enforcement agencies. Therefore, the main reason for allowing a person being arrested to remain silent is to avoid self-incrimination.
