The blackout begins on the eve of the summit, when world leaders arrive in the capital and protesters take to the streets. This comes at the same time as the article about 5 would be bombers at the G20.  http://www.guardian.co.uk/world/2009/mar/30/g20-protest-explosives-plot-arrests

The Department for Transport (DfT) has ruled that Westminster council's mobile road cameras - a third of the authority's CCTV network - "do not fully meet the resolution standards required".

London is a very difficult place to secure, there are thousands of tiny paths and tunnels leading everywhere. If more than a few thousand people enter London with the direct intent to overthrow government, the government wouldn't stand a chance without using weaponry.

There is a real and direct threat to government this week, and they know it. Don't underestimate the power that just a few thousand people will have. They don't want the power of the people shown to the people and the government certainly don't want the evidence of their excessive force on camera for investigation later.

There is a real chance that many could be seriously injured (or worse) in London this week at the hands of our so called "democratic government".

If the government didn't want the public to see what was really happening in London and prevent themselves and law enforcement being held accountable later, they'd take out CCTV and find a way to switch off the communications systems too. No internet. No Mobiles.

As a sales rep for a CCTV surveillance company, I can tell you that problems always arise with the setup of CCTV systems in the public sector.

HOWEVER image quality is always one of the first things a customer looks at. It is NEVER something they overlook, especially since every customer tests samples for 6 months to a year or more if it's under a government contract.

They would have noticed the difference a long time ago!!! Their agent would have all the knowledge about CCTV systems to make sure they get a 720 x 576 CCTV system before investing 15 million on it!

My UK customer supplies to the London metropolitan police, and they use 640 x 480 VGA image quality. Moonwhile the difference between 704 x 576 and 720 x 576 is so minor, no one can tell the difference in quality.

In conclusion from my experience working in a CCTV surveillance company, it is BS! Get prepared for Mayhem!! There's something fishy going on here!!!
