Cui Bono

Latin phrase meaning "who benefits?"

It depends on the fact that crimes are often committed to benefit their perpetrators; especially financially. Usage. The phrase is a double dative construction. It can also be rendered as cui prodest? ("whom does it profit?") and ad cuius bonum? ("for whose good?"). Background.
