Which statement regarding affiants on complaints is accurate?

The statement that only the officer who observed the offense can act as an affiant on complaints is accurate because the role of an affiant is to provide firsthand knowledge of the facts surrounding the case. This requirement ensures that the affiant has directly witnessed the events leading to the complaint, lending credibility and authenticity to the allegation.

Affiants hold a significant responsibility in legal proceedings; their sworn statements serve to establish probable cause and can impact the initiation of criminal charges. By allowing only the officer who directly observed the offense to serve as the affiant, it safeguards the integrity of the information presented to the court and prevents hearsay or unverified claims from influencing judicial processes.

The other options do not meet the requirement for an affiant, as they involve individuals who may not have direct or firsthand knowledge of the offense itself. Only a direct observer can provide the necessary details to ensure that the complaint is grounded in factual evidence.
