Louisiana State Police Academy Cadet Practice Exam

Interfering with a police investigation is a clear example of obstruction of justice because it involves actions that undermine or disrupt the legal process. This can include influencing witnesses, tampering with evidence, or otherwise acting in a way that hinders law enforcement from carrying out their duties. Such behavior can impede the pursuit of truth and justice, and is punishable under various legal statutes.

Helping authorities and cooperating with law enforcement, on the other hand, contribute positively to the justice system. They involve providing assistance or information that can aid investigations, ensuring the proper functioning of legal processes. Refusing to give testimony may also fall under obstruction in certain contexts, but is more about failing to comply with legal obligations rather than actively interfering with an investigation. In contrast, actively interfering with a police investigation directly impacts law enforcement efforts, making it a clear instance of obstruction of justice.
