Which statement about evidence collection is true?

The statement regarding evidence collection that is true emphasizes the critical importance of proper handling procedures to avoid contamination. When evidence is not collected, preserved, or transported according to established protocols, the integrity of that evidence can be compromised. Contamination can occur through various means, such as cross-contamination from other evidence, human interaction, or environmental factors. This is why law enforcement and forensic professionals follow strict guidelines to ensure that all physical, biological, and digital evidence remains in its original state and maintains its authenticity for legal processes.

The other statements provided imply misunderstandings about evidence collection. For example, suggesting that all evidence can be collected without following protocol undermines the foundation on which forensic integrity is built. Additionally, asserting that only digital evidence requires special handling overlooks the fact that many types of evidence, such as biological or physical samples, also demand careful attention and specific collection methods to preserve their validity. Lastly, stating that evidence only needs to be documented minimizes the comprehensive processes involved in evidence collection, preservation, and analysis, which are essential for a successful investigation and prosecution.
