What type of evidence can ASET expect to receive during an investigation?

The correct choice is based on the understanding that during an investigation, a broad range of evidence can be collected to provide a comprehensive understanding of the situation. Relevant evidence can come from multiple sources, including witness accounts and complaints, which may encompass various forms—such as verbal testimonies, written statements, and even physical evidence.

This inclusive approach is essential in investigations to ensure that all perspectives and data points are considered. By allowing for any relevant evidence from witnesses or complainants, ASET can build a more complete picture of the circumstances under review. This not only helps in making informed decisions but also enhances fairness and transparency in the investigative process.

Other options limit the scope of evidence to very specific types, thereby reducing the potential for a thorough investigation. For instance, considering only video evidence or written statements alone would exclude valuable information that could only be conveyed through direct interaction or discussions with witnesses. Similarly, relying exclusively on expert witnesses would restrict the information flow and potentially overlook important insights from individuals directly involved in the matter.
