Three wise monkeys
▻https://en.wikipedia.org/wiki/Three_wise_monkeys#Meaning_of_the_proverb
Just as there is disagreement about the origin of the phrase, there are differing explanations of the meaning of “see no evil, hear no evil, speak no evil”.
In Buddhist tradition, the tenets of the proverb are about not dwelling on evil thoughts.
In the Western world both the proverb and the image are often used to refer to a lack of moral responsibility on the part of people who refuse to acknowledge impropriety, looking the other way or feigning ignorance.[13]
It may also signify a code of silence in gangs, or organized crime.
