↑ Gertz, for the Washington Times. "Like other organized crime groups, triads [...] are engaged in a range of illegal activities such as bank and credit card fraud, currency counterfeiting, money laundering, extortion, human trafficking and prostitution." Triads rarely fight other ethnic mob groups, fighting mainly among themselves or against other triads. However triads were involved in some territorial disputes with the Irish mob, Jewish mafia and others.
↑ Gertz, for the Washington Times. British authorities in colonial Hong Kong dubbed the groups triads because of the triangular imagery.
