Crimes in which the victim is also an offender

Crimes in which the victim is also, ipso facto, an offender typically involve consensual offenses or minors. For example, a drug dealer is deemed to victimize the purchaser, and can be held civilly liable for harm caused by the drugs, pursuant to possibly unconstitutional statutes such as the Model Drug Dealer Liability Act).  However, the purchaser can also be punished criminally for illegal drug possession.

Likewise, the Code of Virginia provides, "Any person 18 years of age or older, including the parent of any child, who (i) willfully contributes to, encourages, or causes any act, omission, or condition which renders a child delinquent, in need of services, in need of supervision, or abused or neglected as defined in § 16.1-228, or (ii) engages in consensual sexual intercourse with a child 15 or older not his spouse, child, or grandchild, shall be guilty of a Class 1 misdemeanor." Notably, juveniles who engage in sexting can be deemed to be both victim and perpetrator.
