Where’s the security?

Protestors on runway halt flights at Stansted airport.

How the hell were these idiots able to even get on the runway? Surely there should be enough security to prevent them from being able to reach the runway.

More puzzling, the article says:

“Due to this event the runway is closed and will continue to be so until further notice. The advice to passengers is to contact their airlines directly who can advise them but we are expecting delays.”

How bloody long does it take to get the police in to haul them off the runway and off to a cell? It certainly shouldn’t take long!
