The purpose of Protocol 128 Supplemental is to provide what?

• A. New Incident
• B. Additional suspect information
• C. Supplemental information to an existing report
• D. Training procedures

Answer: (C)

The main idea is that Protocol 128 Supplemental exists to add extra information to a report that’s already on file. When new details surface after an initial report has been filed, you use this protocol to attach a supplemental entry that links back to the original record. This keeps the investigation’s history intact and creates a clear, auditable trail of updates without creating a separate incident.

Why this is the best fit: it covers any kind of follow-up data—new facts, corrections, witness statements, additional evidence, or changes in details—while preserving the original report as the core document. It ensures updates are properly time-stamped and attributed, so supervisors and investigators can follow the progression of information in one place.

Why the other options don’t fit: creating a new incident would start a separate file rather than augmenting the existing one. Providing only additional suspect information narrows the purpose to a subset of possible updates, whereas the supplemental protocol is intended for any information that expands or corrects the existing report. Training procedures are unrelated to adding information to incident records.
