"In the days of ancient Rome when the republic was still a republic,
Lucius Cassius, one of the city's most venerated consuls, famously
coined the phrase cui bono.
It means As a benefit to whom?, and Lucius Cassius, inquisitive and
analytical by nature, was always asking the question... whether he was
investigating a crime or unraveling political corruption." - Simon
Black
Like I have always said, "Follow the flow of the money it always
reveals the truth."
