اومرتا

Also known as Code of silence, Omerta

Omertà () is a Southern Italian code of silence and code of honor and conduct that places importance on silence in the face of questioning by authorities or outsiders; non-cooperation with authorities, the government, or outsiders, especially during criminal investigations; and willfully ignoring and generally avoiding interference with the illegal activities of others (i.e., not contacting law enforcement or the authorities when one is aware of, witness to, or even the victim of certain crimes).
