What is the difference between “trial by jury” and “trial by accusation”? how is one a “witch hunt”

Trial by jury is, commonly, when the jury is responsible for analyzing the facts of the case, and the judge make the final decision. Trial by accusation is linked to someone's reputation. and suspicions about it. Is more primitive,  so can be described as “witch hunt”, because it goes against the Presumption of innocence, where someone is innocent until proven guilty.
