Hello, Hello, anyone watching?

[Mortblanc]

The entire system is in place based on the ability to prevent exactly the actions that just occurred.

The Terrorist should have never made it to the bottom of the stairs of the tube station, carrying a 5 gallon bucket of who knows what, before he was stopped.

Once the detonation occurred within seconds the CCTV should have been tracing the person that set the bucket down from camera to camera while the police rushed to stop him before he got 2 blocks away from the train.

That was the performance they used to justify the presence of a 24/7/365 watch on every citizen in London.

Either no one is watching the camera system, it is not performing up to the advertised standard, the prevention of terrorism is not the reason for its existence, or (heaven forbid), selected incidents of terrorism are being allowed to justify a pre-planned agenda.
