Why each option
All four options represent foundational principles that forensic investigators must follow to ensure evidence integrity, legal admissibility, and investigative credibility. Each rule addresses a distinct and essential aspect of proper forensic procedure.
Preparing a chain of custody and handling evidence carefully creates an auditable, unbroken record of who accessed evidence and when, which is legally required to establish admissibility and prevent claims of tampering.
Examining original evidence ensures no data is lost due to imaging errors or incomplete duplication, and in some legal contexts investigators must demonstrate familiarity with the original to validate their findings.
Staying within one's forensic knowledge base prevents invalid conclusions, preserves expert witness credibility, and ensures that findings can withstand legal scrutiny without being undermined by competency challenges.
Following rules of evidence and never tampering with evidence is a legal and ethical obligation that preserves the integrity of the investigation and ensures findings are not rendered inadmissible due to mishandling.
