What is often included in a post-incident report?

A post-incident report serves as a critical document that provides an overview of what transpired during a specific incident. It emphasizes the importance of documenting the event in a clear and thorough manner. The report typically includes a detailed description of the incident itself, which encompasses key elements such as the timeline of events, the actions taken by security personnel, and any other relevant activities that occurred.

In addition to the description and actions, it also mentions any witnesses present during the incident, as their testimonies can be vital for understanding the situation better and for any subsequent investigations. This comprehensive information ensures accountability, allows for an assessment of the response to the incident, and aids in preventing future occurrences.

In contrast, the other options do not constitute the essential components of a post-incident report. While knowing the staff present can be useful, it is not as critical as a full description of the incident. Including only the security guard's opinion does not provide an objective account of the events and may lead to biased interpretations. Lastly, while confidentiality is important, the report should not contain sensitive personal information that could compromise the privacy of those involved. Thus, the focus on accurate and complete reporting in option B highlights its significance in the context of incident response and documentation.
