It is only for the sake of emphasis that I would want to add that it is elementary in criminal trial that before an accused person is asked to undergo any sort of sentence, there must be a finding by the trial court on the concurrence-of the two main elements of any crime that is the actus reus and the mens rea. Actus reus is taken to be the wrongful deed that comprises the physical components of a crime and that generally must be coupled with mens rea. Mens rea is the criminal intent or guilty mind of the accused. For the prosecution to establish a criminal act against an accused person, it must go beyond establishing the commission of the unlawful criminal act by the accused but must establish that the accused has the correct legal (criminal) mind of committing the act. The two must co-exist whether explicitly or by necessary implication.
