Which of the following actions is required from law enforcement upon receiving a report of a crime?

The correct answer emphasizes the fundamental duty of law enforcement upon receiving a report of a crime, which is to conduct an investigation. This process is crucial as it allows law enforcement to gather evidence, interview witnesses, and assess the validity and severity of the reported incident. By conducting an investigation, officers can determine if there are sufficient grounds to obtain arrest warrants, ultimately leading to appropriate legal action based on the findings. This step is vital in ensuring justice and maintaining public safety.

In comparison, determining whether a crime warrants press coverage or immediately issuing a press release do not address the necessary investigatory actions that law enforcement must undertake. These steps may be part of managing public relations or communications after an investigation begins but are not foundational responsibilities upon receiving a report. Ignoring false reports also diverges from the appropriate protocol, as law enforcement must at least verify the legitimacy of all reports before deciding on a course of action.
