I don't suppose there is such a thing, but is there an "armed response team time to get to ........XYZ" list?
Are there national criteria such as there are for ambulances and fire appliances?
And if not, why not?
Hereabouts, we have RAF Wittering, which is a long way from anywhere that might just have a team? In S Lincs our ordinary police cover is scanty to virtually non-existent at night: sighting a policeman or police vehicle is such a rare event that people comment on it.
I do not blame the police at all. They are spread thinner than Marmite on my toast.
