A person who knowingly subjects another to an unlawful search can be charged with which offense?

The correct answer is that a person who knowingly subjects another to an unlawful search can be charged with official oppression. This offense typically involves a public servant (such as a police officer) abusing their official capacity to subject a person to an unlawful or improper act. Official oppression encompasses the actions of individuals who misuse their authority to infringe upon someone's rights, which aligns with the act of conducting an unlawful search.

In contrast to the other offenses listed, official oppression specifically addresses the abuse of power by public officials. False imprisonment refers to unlawfully restraining a person against their will, which does not directly relate to the act of unlawfully searching someone. Assault involves causing or threatening physical harm to another person, which is distinct from the violation of privacy that occurs during an unlawful search. Malicious prosecution pertains to wrongfully instituting legal proceedings against an individual without probable cause, and is therefore not applicable to the scenario of conducting an unlawful search.
