The Outdated Hurricane Brief
Constable Reid has just been posted to a rural station in St. Elizabeth. With two hours before a community hurricane-preparedness meeting at the church hall, she has three conflicting sources. A 2019 ODPEM leaflet says the hall can shelter 120 people. A parish council notice, dated last month, says the hall roof was repaired and the safe capacity is now 90. A WhatsApp voice note, forwarded 40 times, says the hall has been closed as a shelter and residents should use a school 6 km away. The station radio is out for repair, the sub-officer is on patrol and cannot be reached, and Reid's phone has 18% battery. Forty residents are expected, including 12 elderly people and 9 children under 12. The church hall has a landline. Reid must decide what to announce, what to verify first, and how to avoid causing panic or sending vulnerable people on an unnecessary 6 km trip.
1. Rank the three sources for reliability on the two questions Reid must answer: (a) how many people can safely shelter in the hall, and (b) whether the hall is open as a shelter tonight. Explain how the ranking changes between (a) and (b).

Start by separating the two questions, because one source can be best for one and not the other.
For (a) capacity: the parish council notice is the strongest of the three. It is dated last month, it refers to a specific building, and it gives a post-repair figure of 90. The 2019 ODPEM leaflet is authoritative on general shelter procedure, but its 120 figure predates the roof repair, so it is stale on capacity. The WhatsApp voice note gives no capacity and no date; it cannot be checked against a named officer or document, so it is weakest.
For (b) open status: the ranking changes. ODPEM and the parish council are the bodies that can confirm whether a building is activated as a shelter. A parish notice about roof repairs does not prove activation. The WhatsApp note is still weakest, but Reid cannot treat the council notice as proof of opening either.
Reasoning rule: prefer the source that is closest in time, closest to the specific decision, and issued by a body with responsibility for that decision. Recency without authority is weak; authority without recency is stale; a viral message without provenance is not evidence.
2. With two hours, 18% battery, and a landline in the hall, set out Reid's first four actions in order. Justify the order, and say what she should not do.

Use the hall landline, not the cellphone, to call the parish council and ODPEM. Ask two closed questions: 'Is the church hall activated as a shelter tonight?' and 'What is the confirmed safe capacity?' Write the name of the person, the time, and the number called. Reason: verification comes before announcement, and the landline protects the 18% battery for the meeting itself.
Ask the council or ODPEM for a public information number and a short official message that residents can be given. Reason: residents need a source they can contact after the meeting; a number is more useful than a reassurance.
Write three headings on a board or paper - Confirmed, Not confirmed, Action - and put only verified facts under Confirmed. Reason: separating certainty from rumor prevents the WhatsApp claim from being repeated as fact.
Before the meeting, ask one or two residents with charged phones to help share the official number, and identify who can assist the 12 elderly residents and 9 children if transport is needed. Reason: the vulnerable group is the operational priority, not the crowd size.
Do not: repeat the WhatsApp claim as if it were true; send people 6 km without confirmation; use the cellphone for long calls; or promise that the hall is open before the council or ODPEM confirms it.
3. Draft the three key messages Reid should give, label each as confirmed or not confirmed, and explain why the labels matter.

Message 1 (confirmed, if the council confirms): 'The parish council says the hall roof was repaired and the safe capacity is 90 people. We will admit up to that number.' If the council does not confirm, mark it 'not confirmed' and do not use the number as an instruction.
Message 2 (confirmed after verification): 'No official closure notice has been confirmed. The WhatsApp voice note is not an official notice.' This is a statement about the state of the evidence, not a claim that the hall is open.
Message 3 (not confirmed): 'A voice note says the hall is closed and you should go to the school 6 km away. That claim has not been verified; do not act on it until we confirm.'
Why labels matter: residents make safety decisions - whether to walk 6 km with children, whether to leave home, whether to shelter - on what they believe is certain. If Reid mixes confirmed and unconfirmed information, the rumor gains the authority of the uniform. Labelling also protects the station: if the notice later proves wrong, the record shows what was verified, when, and with whom. Finally, it gives the audience a way to judge future messages: they learn to ask 'who confirmed it?' rather than 'how many shares did it get?'
