The description in the question refers to a "qualified" or "trained" individual in security or loss prevention, but none of the answer choices-Engaged liaison, Review personnel, Supportive person-specifically identify a person already knowledgeable in loss prevention and security. Therefore, "None of the above" is the correct choice as it best fits the context.
Engaged liaison (A) refers to someone facilitating coordination, not necessarily with security knowledge.
Review personnel (B) and Supportive person (C) are too generic and do not accurately define a trained security professional.

The three primary types of cost estimates used during the implementation of a physical protection system are:
Budgetary: Initial estimate for planning and approval.
Preliminary design: Estimate based on conceptual design.
Final design: Detailed cost based on approved construction documents and specifications.
This staged estimation approach helps refine costs as the design evolves.
Other options mention contingency or maintenance, which are important but not considered one of the three standard estimating stages.

The statement is incorrect. The correct definitions are:
Libel is written defamation-false and damaging statements published in writing or other fixed mediums.
Slander is oral defamation-spoken false statements meant to damage someone's reputation.
So, libel is not oral; slander is.

Piecemeal security refers to the ad hoc or fragmented implementation of security measures without an overarching strategic plan. Security elements are added reactively, often after an incident or perceived risk, rather than being guided by a coordinated risk assessment. This results in inconsistent, sometimes redundant or ineffective protection efforts, leaving gaps in security coverage.

Security consultants are often retained to provide strategic input on staffing needs, policy design, and technology integration. Their advice helps organizations make informed decisions regarding the deployment of personnel, the structure of policies, and the selection of physical and electronic security systems.
