Final answer:
Licensees are prohibited from engaging in specific acts such as following someone without consent, forcibly removing individuals, reporting on a tenant's activities to landlords, and divulging information about individuals in witness protection, each violating ethical or legal standards for privacy, assault, confidentiality, and safety.
Step-by-step explanation:
The question specifically addresses the type of activities licensees are prohibited from engaging in, with a focus on ethical and legal standards. The prohibition against licensees involves several scenarios: A) Following someone without their consent for the purpose of gathering information, which can infringe on privacy rights and be considered stalking in certain jurisdictions. B) Forcibly removing an unwanted patron from a nightclub, which could lead to charges of assault or battery. Actions seen as violating civil rights or exceeding the bounds of reasonable force are typically prohibited. C) Assisting an apartment owner by informing on a tenant's activities could potentially break privacy laws and the expectation of confidentiality in certain situations. Lastly, D) Providing information about a person in a witness protection program is strictly prohibited due to the safety risks and legal repercussions associated with the disclosure of such sensitive information. Reviewing the historical context, after the end of Prohibition in 1933, state liquor authorities had the power to revoke licenses of bars catering to the gay and lesbian community, which showcases the regulatory power licensees need to be aware of. Moreover, compliance with law enforcement practices, such as avoiding entrapment schemes and selective enforcement, is essential for licensees to operate legally and ethically.
