Step-by-step explanation:
The standard of proof in a criminal case, 'guilty beyond a reasonable doubt,' is an important protection of individual rights because it ensures that an accused person is presumed innocent until proven guilty. This high standard of proof places the burden on the prosecution to present strong and convincing evidence that leaves no reasonable doubt of the defendant's guilt. By requiring such a high level of certainty, it helps to prevent wrongful convictions and protects individuals from being unjustly accused or punished.
