The phrase "wall of silence" often refers to a situation in which people refuse or are unwilling to speak out about a particular issue, often due to fear of reprisal or punishment. Some possible synonyms for this phrase include code of silence, conspiracy of silence, culture of silence, omertà, and stonewalling. Each of these terms conveys a similar sense of secrecy, reticence, or concealment, and can be used to describe situations in which information is deliberately withheld or suppressed.
