What is an important factor that demonstrates the integrity of evidence?

The integrity of evidence is crucial in any investigation or legal proceeding, as it impacts the reliability and validity of the findings. An important factor that demonstrates the integrity of evidence is that it should not be altered or changed. This principle ensures that the evidence remains in its original state, allowing for accurate analysis and interpretation by forensic experts, as well as preserving its admissibility in court.

When evidence is unaltered, it maintains its chain of custody, meaning that it can be traced back to its original collection, thereby supporting its authenticity. Any changes made to evidence can lead to questions regarding its validity and may undermine the entire case. This principle is foundational to the legal system, as it upholds the standards of justice and fairness in the investigation process. In contrast, if evidence were to be manipulated or discarded, the integrity of the entire investigation could be called into question.
