What is the critical role of chain of custody in speed detection evidence?

The critical role of chain of custody in speed detection evidence is to ensure evidence reliability from the moment of detection through presentation in court. Establishing and maintaining a proper chain of custody is essential because it documents the handling of evidence at every stage, from when it is collected at the scene to when it is presented in court. This process involves careful logging of who collected the evidence, who handled it afterward, and the conditions under which it was stored and transported.

By maintaining a clear and documented chain of custody, law enforcement and legal professionals can show that the evidence has not been altered or tampered with, thereby preserving its integrity. This assurance is vital when the evidence is scrutinized in court, as it supports the credibility of the findings from the speed detection equipment. Without a solid chain of custody, the reliability of the evidence may come into question, which could ultimately affect the outcome of legal proceedings.
