Circumstantial evidence
Reasonable doubt is tied into circumstantial evidence as that evidence relies on inference. It was put in place because the circumstantial evidence may not be enough to convict someone fairly. Reasonable doubt is described as the highest standard of proof used in court and means that a juror can find the defendant guilty of the crime to a moral certainty. Circumstantial evidence against someone may not be enough to convict or find innocent, but it can contribute to other decisions made about the case.
