What is Indecent Exposure?

Legal Definition
As a legal expression, indecent exposure is the deliberate exposure in public or in view of the general public by a person of a portion or portions of his or her body, in circumstances where the exposure is contrary to local moral or other standards of appropriate behavior. Social and community attitudes to the exposing of various body parts and laws covering what is referred to as indecent exposure vary significantly in different countries. It ranges from outright prohibition to prohibition of exposure of certain body parts, such as the genital area, buttocks or breasts.

Decency is generally judged by the standards of the local community, which are seldom codified in specifics in law. Such standards may be based on religion, morality or tradition, or justified on the basis of "necessary to public order". Non-sexual exhibitionism or public nudity is sometimes considered indecent exposure. If sexual acts are performed, with or without an element of nudity, this can be considered gross indecency, which is usually a more serious criminal offence. In some countries, exposure of the body in breach of community standards of modesty is also considered to be public indecency.

The legal and community standards of what states of undress constitute indecent exposure vary considerably, and depend on the context in which the exposure takes place. These standards have also varied over time, making the definition of indecent exposure itself a complex topic.
