Evidence is defined as any type of information that can be used to prove a fact or support a statement. This includes physical items, documents, witness statements, and other types of evidence. Evidence can be divided into two main types: direct evidence and circumstantial evidence. Direct evidence is evidence that directly proves or disproves a fact. Examples of direct evidence are eyewitness testimony, physical objects, and confessions. Circumstantial evidence is evidence that suggests a certain fact without directly proving or disproving it. Examples of circumstantial evidence are patterns of behavior, circumstantial evidence of motive, and circumstantial evidence of opportunity. Evidence is a critical component of any legal case. It must be relevant, reliable, and admissible in court for it to be used in a case.
