This document discusses evidence and its assessment in legal cases. It defines evidence as the basis for belief or disbelief, and typically includes witness testimony, documents, photographs, and other materials. Evidence must be relevant to the case and admissible in court. There are several types of evidence, such as direct, circumstantial, forensic, and documentary evidence. For evidence to be admitted, it must pass tests for relevance and reliability. Prosecutors must also consider whether there is a realistic prospect of conviction based on the evidence and whether prosecution would be in the public interest based on factors for and against prosecution.
