What is the main purpose of a DHS Form 3155?

The correct answer highlights the primary function of a DHS Form 3155, which is to serve as an official record detailing important information about a crime or incident. This form is crucial for documenting events accurately and concisely, allowing law enforcement and security personnel to maintain a reliable account of occurrences. By capturing the essential facts, the form contributes to operational transparency and can support subsequent investigations or legal processes.

The other options do not align with the fundamental role of the form. It doesn't focus on convicting individuals or protecting personnel from wrongdoing; rather, it is about record-keeping and ensuring proper documentation. Additionally, while the form may contribute to compliance and professionalism in the eyes of supervisors, that is not its main intended purpose. The emphasis is placed on its function as a record rather than on perceptions of individuals involved in the reporting.
