Surely in this country we have 'other resources' available for this sort of thing.
'Resources' on 24/7 standby with the ac correctly fuelled, crewed and role'd. Able to land ad hoc under 'black light' with practised and current crews, carrying trained and practised 'firearms persons'.
Look at West Cumbria and Derek Bird....(and then they used the Firearms guys from Windscale and an RAF SAR cab).
