Booby-traps are primarily designed to accomplish what?

Booby-traps are primarily designed to cause harm or injury. They are hidden devices or setups that, when triggered, can inflict damage or create dangerous situations for unsuspecting individuals. This definition aligns with the underlying intention behind the creation of such devices, which is to entrap or injure individuals rather than serve a benign purpose like warning, communication disruption, or security enhancement.

In the context of security and law enforcement, recognizing the use and purpose of booby-traps is crucial. While the other options might hint at various methods or tools intended to protect or alert, they do not accurately capture the inherently malicious design of booby-traps. Their purpose is not to enhance security but rather to pose a threat, thereby making it important for peace officers to be aware of their potential presence in various environments and to take necessary precautions.
