There is no hard evidence to support what you are stating. In most western countries the justice rule applies that everyone is innocent till proven otherwise. As such, untill you have hard evidence against Tyrant you have no right to accuse this person of confidence trick.
Furthermore, what you are doing is considered illegal in itself. Defamation is just as punishable as confidence trick.
