The Truck That Would Not Stop
02:10. A guard is posted at the outer gate of a water-treatment facility classified in the site's security plan as critical infrastructure. The gate is a boom barrier with a concrete blockhouse 4 m to the side; there are no tyre spikes and no bollards. A pickup truck approaches the outer gate at about 40 km/h, does not slow, and stops 3 m short of the barrier with a squeal of brakes. It reverses 20 m, then comes forward again at the same speed and stops in the same place. The windows are dark; the guard's challenge by voice and over the intercom gets no answer. The driver revs the engine. The second guard, inside the blockhouse, says over the radio, 'Shoot the tyres, that will stop him.' The guard carries a pistol with 15 rounds and a radio, magazine inserted and a round chambered per this site's carry order. The yard is empty; a night shift of three is working in the control building 80 m inside the fence.
1. Is shooting at the tyres an authorised or lawful option here? Reason it through rather than answering yes or no.

No, on several independent grounds.
The interest at stake: what is currently threatened is a boom barrier and a fence. Firearms protect life, not installations. Nothing in the scenario yet shows a threat to a person.
The act itself: firing at a vehicle is a lethal-force act regardless of where the muzzle is pointed. A tyre is a small, curved, moving target; rounds ricochet off rims and tarmac, and a driver who is shot at, wounded, or suddenly deprived of a tyre at speed becomes an uncontrolled vehicle heading into the yard where three people are working. Rounds that miss travel somewhere.
The tactic fails on its own terms: a deflated tyre does not stop a determined driver, and the guard is standing near the barrier, in the path, with the vehicle 3 m away. He is creating a collision risk instead of reducing one.
The rule of last resort: the weapon is available when there is an imminent threat to life that cannot be met another way. A truck that approaches, stops, reverses and approaches again without answering is suspicious and reportable - it is not yet an attack. The correct escalation is physical and observational, not ballistic.
2. Give the tactical sequence from the second approach until the vehicle either leaves or breaches the barrier.

- Get behind the concrete blockhouse, not behind the barrier. The barrier is a speed bump; the concrete is cover. The guard's first move is lateral and immediate.
- Keep the barrier down, keep the inner gate locked, and tell the control room over the radio to lock the inner perimeter and keep the three workers inside.
- Call 100 with the location, the vehicle description, the plate as far as it is readable, the direction of approach and the fact that the driver is not responding. The second guard does this while the first keeps observation - one pair of eyes stays on the vehicle at all times.
- Do not approach the vehicle, do not stand in front of it, do not walk up to the driver's window, do not lean in.
- Observe and record: time, plate, make, colour, number of occupants if visible, damage, any markings.
- If it breaches the barrier, the guard stays behind cover and does not chase a moving vehicle on foot. If it crashes or stops inside and occupants emerge unarmed, he challenges from cover and waits for police.
- The weapon comes up only if a person's life is imminently threatened - for example the truck is driven deliberately at a person who cannot escape, or armed occupants emerge and advance. Then the analysis changes from property to self-defence, and the shot must still meet necessity and background-safety requirements.
3. The truck turns and leaves. Assemble the post-incident actions, in the order that matters.

The single time-critical item is the footage: CCTV is routinely overwritten on a rolling cycle, and a request 'tomorrow morning' can be a request for nothing. Call the control room or the site security officer immediately and have the relevant cameras exported and preserved, with the correct clock offset noted - site systems are often minutes or hours off true time, and that discrepancy is exactly what a police investigator will ask about.
Then, in order: a call to police 100 and a written statement the same shift; an entry in the site incident log covering time, plate and partial plate, vehicle description, direction of travel, number of occupants if seen, warnings given and rounds fired (none); notification up the chain - shift supervisor, facility manager, the site's security officer - because a probe of critical infrastructure is a national-level reporting matter, not just a gate log entry; a perimeter check with the second guard, and a check of the inner gate and the fence line for anything left behind.
Finally, an honest self-review: was the guard's position correct before the vehicle arrived, was the challenge audible, and does the site need bollards or spikes - because the answer to 'shoot the tyres' is a physical barrier, requested in writing, not a pistol round.
