Might be worth considering the likely normal daily activities of 2 low ranking police officers, one in a tough / deprived inner city area, and the other in a rural village.
Both have sworn the same oath, but they are likely to have different day-to-day priorities. There are plenty of things that have to be ignored in a sink estate that would be picked up by a village resident.
I'm not saying Gatwick is under attack from rioters, but it likely has rather bigger problems and credible security threats compared to Newquay.
