Which statement accurately describes the independent source doctrine?

• A. The exclusionary rule applies even with an independent source
• B. The presence of any illegal search invalidates all evidence
• C. All evidence derived from an illegal search is excluded
• D. If the prosecution can show the illegally obtained evidence was also derived from an independent source, the exclusionary rule may not apply

Answer: (D)

The independent source doctrine allows evidence to be admitted if it was discovered through a source wholly independent of any illegal police conduct. The key idea is that the information leading to the discovery comes from a lawful, separate path, not from the tainted illegality. When the prosecution can show that the illegally obtained evidence also stemmed from an independent, lawful source, the exclusionary rule may not apply to that portion of the evidence because its discovery wasn’t dependent on the illegal act. This is why the statement that best fits is that the exclusionary rule may not apply if the illegally obtained evidence was also derived from an independent source. In contrast, the other ideas are too sweeping or incorrect: the rule isn’t automatic in every case of an illegal search, and not all evidence derived from an illegal search is necessarily excluded if there’s an independent source showing lawful discovery.
