At a crime scene there are numerous procedures that need to be followed in order to ensure that the crime scene is kept secure, and that the evidence is at the crime scene is preserved, as much as possible. If these procedures are not followed correctly then the evidence that is collected at the scene could be compromised, which ultimately stops a case from ever going to court.
In the Siôn Jenkins case it is clear to see what procedures were and weren't followed, and it is well documented what evidence was collected, how the evidence was collected and how the evidence was analysed.
