Final answer:
Wiretapping is the correct answer as it is a form of surveillance usually reserved for law enforcement officials due to the need for legal authorization to intercept private communications.
Step-by-step explanation:
The question Which of the following is a form of surveillance that is usually only available to law enforcement officers? refers to specific techniques that are typically used by law enforcement agencies to monitor suspects or areas for security purposes. Among the options provided:
- Surveillance using video cameras
- Wiretapping
- Stationary surveillance
- Tailing
Wiretapping is the correct answer because it involves intercepting and listening to private conversations—a form of surveillance that generally requires legal authority and is closely regulated. This practice often requires a warrant, and in the context of fighting terrorism or criminal activity, is a tool predominantly used by law enforcement and intelligence agencies. Surveillance using video cameras, stationary surveillance, and tailing can be also utilized by private individuals and entities, making them less exclusive to law enforcement.
Despite the benefits of surveillance in enhancing security and public safety, technology has raised concerns about privacy rights and the potential for misuse. Societal debates continue weighing the value of thorough monitoring against the intrusion on individual freedoms and civil liberties.
