______ is the act of viewing, observing, or invading the privacy of a person without their consent for the purpose of sexual gratification.

The act being described involves observing or invading someone’s privacy specifically for sexual gratification. Voyeurism fits this definition perfectly, as it is characterized by the act of gaining sexual pleasure from watching others when they are naked or engaged in sexual activity, often without their knowledge or consent. This behavior is both invasive and non-consensual, highlighting the violation of personal privacy that is central to voyeuristic acts.

Surveillance refers to the general act of monitoring or observing individuals or groups, often for security or investigative purposes, and does not necessarily involve a sexual component. Videotaping surveillance is a more specific form of surveillance that involves recording, generally for legitimate purposes such as law enforcement or business security. The Peeping Tom Law violation pertains specifically to laws enacted to criminalize the act of peeping at individuals without their consent but does not encompass all voyeuristic behavior.

Thus, voyeurism is the most accurate term for the scenario described, as it directly addresses the motive of sexual gratification and the lack of consent inherent in such actions.
