Why didn't they just shoot down the drone that shut down Gatwick Airport today?

It would take a good marksman to hit a small moving target at distance but there was a picture of a marksman so it was something they were prepared to attempt.

It is much easier to "shoot down" those controlling the drones.

Thickness compounded by utter stupidity.

I agree, but suppose they (the military?) can't just bang off bullets in the hope of bringing down these drones.

Keeps disappearing and reappearing. They need lasers and a high powered sighting system.

They really should of, but I guess they were following protocol.

Everyone overlooks the simple answer.

That would have been against protocol
