Under which amendment of the U.S. Constitution is a citizen protected against self-incrimination?

The protection against self-incrimination is found in the 5th Amendment of the U.S. Constitution. This amendment provides that no person "shall be compelled in any criminal case to be a witness against himself," which means individuals have the right to refuse to answer questions or provide information that could potentially incriminate them in a criminal proceeding. This protection is a fundamental aspect of ensuring fair legal processes and upholding the principle of justice by preventing coercion during interrogations or trials. It reflects the understanding that the government must bear the burden of proof in a criminal case and that individuals should not be forced to assist in their own prosecution.
