Review Questions

• How does the chain of custody impact the admissibility of evidence in court?
  • The chain of custody is critical for determining whether evidence can be admitted in court. If there are gaps or inconsistencies in the documentation of who handled the evidence and how it was preserved, it can lead to questions about its integrity. Courts may exclude evidence that cannot be clearly traced back to its original collection, as this raises concerns about potential tampering or contamination.
