Critical infrastructure

I am rather perturbed by what looks like a total failure by Gatwick Airport to have any plans or tools available to meet threats from drones, despite the threat having been around for years now. What other threats are they not doing anything about?

At one level, this can be seen as a for-profit private company (the Global Infrastructure Partners of reference 1, who own Gatwick), dumping the costs of dealing with this particular threat on government. With their insurers picking up the tab for the damage? Rather as the ship owners dumped the costs of dealing with pirates off the Horn of Africa on government (reference 2).

A for-profit company which appears to be mainly staffed up, at a senior level, by people who have done time with Credit Suisse. Is it really owned by some sovereign fund from some rogue state, keen to discretely disrupt things over here?

My own solution would be a shot gun. I can't see that letting off a shot gun at the perimeter fence at Gatwick would be likely to present any threat to passers by, and I would have thought that a shot gun would be more than enough to take out a small drone. But I don't suppose it will happen: we seem to be getting terribly squeamish about such things and would rather spend millions on hi-tech toys for the security boys.
