Another important detail about the apparent lack of Stockwell Tube station CCTV "evidence" which might have shed light on the killing of the innocent Brazilian Jean Charles de Menezes - the BBC reports:
"The BBC has also learned the shooting was not captured on Stockwell Tube's CCTV because police officers had removed the cameras' disks for their investigation into the suicide bomb suspects who boarded the train at the same station the previous day."
How many other CCTV cameras have been disabled , not due to terrorist attacks, but due to police investigation "collateral damage" ? What is so difficult about copying digtial dat to another disk (with apprpriate chain of evidence digital signatures etc.) ? Why are there insufficient spare disks or tapes etc. for this to be accomplished as a standard routine procedure ?
Were these "disks" actually physically removed from Stockwell Tube Station, or is this alleged incompetence more widespread at the central systems in the British Transport Police CCTV Camera control room between Victoria and Battersea ?
N.B. despite claims that there are now over 6,000 CCTV surveillance cameras trained on the the London Underground and mainline railway stations, there is in fact, a multiplicity of different systems, using different technologies and equipment, of varying ages and reliability. It is not true that all cameras work all the time, or that they constitute a single, easily controlled "Big Brother" surveillance system - that is probably the intention, but, it has not yet been achieved in practice.
Neither has there been any noticable reduction in crime, as a result of all these extra surveillance systems, and, very obviously, there has been no deterrent effect on terrorists.
How many other CCTV systems have been disabled by the anti-terrorist investigations ?
There are still no media reports or even questions about whether or not there is any CCTV footage available from the Number 2 Bus which Jean Charles de Menezes and the surveillance team waited for and boarded for over 20 minutes.
It really is time to learn the lessons from the terrorist attacks in July, and for the Government to now regulate and licence all CCTV surveillance camera operators to ensure minimum operational and maintentance standards throughout the country, as well as fair and equal legal access to such systems for all.
