What challenges arise when forensic evidence sent by police is incomplete or incorrect in sensitive cases?

Forensic evidence plays a critical role in criminal investigations, especially in sensitive and high-profile cases. The quality and accuracy of evidence sent by police can significantly impact the investigation process and the ultimate delivery of justice. When forensic evidence is incomplete or incorrect, several challenges arise:

• Delay in Justice: Incomplete or incorrect evidence can lead to delays in investigations, as forensic labs may request resubmission or clarification, slowing down the entire process.
• Wrongful Convictions or Acquittals: Poor quality evidence increases the risk of innocent people being convicted or guilty individuals being acquitted, undermining faith in the justice system.
• Loss of Crucial Evidence: Mishandling or incomplete documentation can result in the loss or contamination of key evidence, making it unusable in court.
• Compromised Investigation: Investigating agencies may be unable to establish the sequence of events or motive due to gaps in forensic evidence, affecting the overall investigation.
• Legal Challenges: Defence lawyers can exploit errors or gaps in forensic evidence to challenge the credibility of the prosecution's case, leading to prolonged trials or acquittals.
• Public Distrust: In sensitive or conflict situations, errors in forensic evidence can fuel public suspicion and erode trust in law enforcement agencies.
• Resource Wastage: Repeated testing and re-examination due to incomplete or incorrect submissions waste valuable time and resources of forensic laboratories.
• Psychological Impact: Victims and their families may suffer prolonged trauma due to delays or miscarriage of justice resulting from poor forensic practices.
