It is against the law in Washington, D.C. for a person to exposure a part of his/her body in an obscene or indecent way or to make any lewd, obscene or indecent proposal. The law would not apply to a woman breast-feeding a baby. In one case that tested the statute, the law was not found to apply to a protester wearing only a placard because the protester’s genitalia were not visible.
The offense is punishable by a maximum fine of $300 and/or up to 90 days in jail. If, however, the act is knowingly committed in the presence of a child under the age of 16 years old, the penalty increases to a fine of up $1,000 and imprisonment for up to 1 year. D.C. Criminal Code § 22-1312.
