It is the action of hiding, covering, protecting or concealing a gesture or motive for something or someone. In the area of communication, concealment is the disguise of messages through language or words that are considered offensive or inappropriate (blind instead of blind, person of color instead of black, negative growth to refer to decrease and a long etc).
In the communicational area, a message is covered up or distorted to make it more attractive or avoid the use of phrases with negative connotations in any sense. Another concealment strategy is the use of circumlocution, it is when detours in an explanation are warranted or not saying things directly and bluntly. There are mechanism variables in language used to cover up, such as: irony, double meaning, figurative language or the use of metaphors.
In the case of criminal acts, it is when someone commits a crime and may need someone else so that that illegal action is not known, the person coerced or the person who helps the offender who is also punished by law, for being a collaboration illegal that hinders the role of justice. The role of the cover-up is someone who provides an alibi to the offender even if they have not participated directly in the criminal act, since with their action they are favoring the offender.
In law, the crime of concealment is subject to controversy and debate, in the case of parents who do not report their children for a crime, since it is more of a moral dilemma than concealment, but when assessing the accusation it is done difficult to determine if it is illegal or not. Legally, the cover-up would also affect parents, but legally there is an open debate about what penalties should be applied to direct relatives who cover up their relatives, since in the case of parents they are obliged to protect their children.
