The Impact and Limitations of Forensic Evidence

Forensic evidence in criminal cases is often viewed as objective and hard to disprove, given its empirical nature. However, it's not without limitations. Human error in evidence handling can lead to miscarriages of justice, highlighting the need for meticulous procedures.

Example: The Adam Scott case illustrates the potential for evidence contamination. Scott was wrongly accused of rape due to a DNA sample tray being reused, leading to cross-contamination.

Example: In the Amanda Knox case, the late discovery of a bra strap (47 days after the crime) raised questions about evidence deterioration and proper crime scene investigation.

Example: The Stephen Lawrence case revealed how mislabeling evidence can lead to misinterpretation. A leather bag strap found near the scene was incorrectly logged as being 90 yards away instead of 11 yards, causing it to be overlooked for 21 years.

Witnesses: A Critical Influence on Trial Outcomes

Witness testimony can significantly influence trial outcomes. If jurors find a witness believable and reliable, they are more likely to side with the party that witness represents. Conversely, an unreliable witness can undermine the credibility of the side they support.

Vocabulary: Inculpatory evidence refers to evidence that shows, or tends to show, a person's involvement in an act, or evidence that can establish guilt.

Rights of witnesses in criminal investigations and court proceedings are crucial aspects of the justice system. These rights ensure fair treatment and protect witnesses from intimidation or undue pressure. Understanding these rights is essential for both witnesses and legal professionals involved in criminal cases.

Vocabulary: The Witness Charter is a document that sets out the standards of care and support that witnesses can expect from the criminal justice system in England and Wales.

Who is present during a significant witness interview can vary depending on the nature of the case and the witness's circumstances. Typically, the interviewing officer(s), the witness, and potentially a legal representative or support person may be present. In cases involving vulnerable witnesses, specially trained officers or intermediaries might also attend.

Example: For a child witness, a parent or guardian and a specially trained child interview specialist might be present during the interview to ensure the child's well-being and the integrity of the evidence gathered.

Can the accused see witness statements UK? Generally, the accused has the right to see witness statements as part of the disclosure process. However, there are exceptions to protect vulnerable witnesses or in cases where revealing the identity of a witness could compromise their safety or the integrity of the investigation.

Highlight: The prosecution may apply for witness anonymity in certain cases where there is a real and immediate threat to the safety of the witness if their identity is revealed.

Rights of witnesses in court include the right to be informed about court proceedings, to be protected from intimidation, and to have access to support services. Witnesses also have the right to claim expenses for attending court and to request special measures if they are vulnerable or intimidated.

Definition: Special measures are provisions that can be made to help vulnerable or intimidated witnesses give their best evidence in court. These may include giving evidence behind a screen or via video link.

What is the problem with the Witness Charter? While the Witness Charter sets out important standards, its implementation can be challenging. Some critics argue that it lacks legal enforceability and that the level of support provided to witnesses can vary depending on resources and local practices.

Highlight: One challenge is ensuring consistent application of the Charter across different jurisdictions and cases, particularly in resource-constrained environments.
