Techniques on Gathering Evidence

A. Collecting Physical Evidence

1. Conducting Searches:

   • Warrant Requirements: Understand the legal requirements for conducting searches, including obtaining search warrants if necessary under the Crimes Ordinance. For example, if a law student is involved in a case where evidence is believed to be located in a suspect's home, they must ensure that a proper warrant is obtained to avoid legal repercussions.

   • Documentation: Document the search process meticulously, noting the time, location, and items collected. Use photographs for visual documentation. For instance, in a case involving a traffic accident, taking photos of the accident scene can provide valuable evidence.

2. Chain of Custody:

   • Maintain Records: Keep detailed records of who collected the evidence, how it was handled, and where it was stored. This is crucial for establishing the integrity of the evidence later in court. For example, if a student collects a piece of physical evidence, they should document every person who handles it to maintain a clear chain of custody.

3. Proper Handling Techniques:

   • Use gloves and appropriate tools when handling physical evidence to prevent contamination. For example, in a case involving drug evidence, improper handling could compromise the integrity of the evidence.

   • Store evidence in secure, labeled containers to ensure its protection and integrity. For instance, biological samples should be stored in refrigerated conditions to prevent degradation.

​

B. Collecting Digital Evidence

1. Legal Considerations:

   • Ensure compliance with the Personal Data (Privacy) Ordinance when collecting digital evidence. Obtain necessary permissions or warrants when accessing personal devices or accounts. For example, if a student needs to access a client's email account for evidence, they must ensure that they have the client's consent.

2. Forensic Tools:

   • Use forensic software to create bit-for-bit copies of digital evidence. This ensures that the original data remains unaltered. For instance, in a fraud case, creating a forensic image of a suspect's computer can preserve evidence for analysis.

3. Preservation Techniques:

   • Secure devices in a manner that prevents data loss or tampering. Document the process of collecting digital evidence, including any passwords or encryption methods used. For example, if a student collects a smartphone as evidence, they should document the phone's condition and any relevant passwords.

​

C. Collecting Testimonial Evidence

1. Interview Techniques:

   • Build Rapport: Establish a comfortable environment for witnesses to share their information. Use open-ended questions to encourage detailed responses. For example, in a personal injury case, asking a witness to describe what they saw in their own words can yield more information than leading questions.

   • Recording Interviews: Obtain consent to record interviews (audio or video) for accuracy. If recording is not possible, take thorough notes during the interview. For instance, in a witness interview for a criminal case, recording the conversation can help ensure that no details are missed.

2. Witness Preparation:

   • Prepare witnesses for what to expect during their testimony. Discuss the importance of honesty and clarity in their statements. For example, if a witness is nervous about testifying in court, providing them with a mock trial experience can help alleviate their fears.

3. Affidavits and Statements:

   • Encourage witnesses to provide written statements or affidavits, which can enhance the credibility of their testimony in court. For instance, in a civil case, a signed affidavit from a witness can serve as powerful evidence.

​

D. Collecting Documentary Evidence

1. Document Requests:

   • Prepare requests for documents from clients or third parties. Clearly outline the types of documents needed and the purpose for their collection. For example, in a corporate dispute, a student might request financial records to support their case.

2. Public Records and Databases:

   • Utilize public records and online databases to gather necessary documentation. This includes court records, land registries, and government databases. For instance, accessing the Hong Kong Land Registry can provide crucial information about property ownership.

3. Organizing Collected Documents:

   • Create a systematic filing system for organizing collected documents. Use digital tools for easy retrieval and sharing with colleagues. For example, using cloud storage solutions can facilitate collaboration among team members working on the same case.
