This is the only correct answer. Nobody moves across a runway unless ATC clears them. They did. They they actually looked at that big green screen with the flying things on it - realized they cleared one to land - and tried to stop a moving fire truck halfway across a runway.
Now the question becomes - was there only one ATC guy, were they short, and when are there going to be enough ATC people that these accidents stop happening.
Personally I would add in: when are the authorities going to re-test everyone to weed out the ones that were approved by cheating or DEI.
Even with clearance, it's the operators job to check if the runway is clear, before crossing: it was the job of the trunk's operator to check right/left/center to make sure the runway was clear. That plane on arrival, with the landing lights on, would have been hard to miss.
