In the 'real world' low tech loners and sleepers marauding with freely available weapons is a tactic that is impossible to completely guard against, even in authoritarian locked down zones like the West Bank of Israel let alone the West Bank of London. The only comfort from this sort of pointless barbarism is that the Brit's have seen worse and not been phased, and using radicalised psychopaths on suicide missions smacks of desperation.
Maybe my point was lost a little....this guy was on the watch list, he was known to MI5, his face would have been on the database...I completely agree it's almost impossible to stop an unknown creating havoc, but surely the people we have marked on an MI5 watch list should be easy to spot coming into a high target area like Westminster....or am I missing something?!
Are you seriously suggesting that technology is available that can reliably scan a face (driver? rear passenger?), possibly wearing shades, hat etc in a moving hire vehicle? even UK border control requires you to stand still, no glasses and look directly in to the camera and moving CCTV of people on foot (let alone in a vehicle) is currently wildly unreliable. The thing you ARE missing is that the US and other Western protagonist have tried increasingly high tech responses which give a false sense of security against low tech, low profile terrorist. The UK has a solid background of 'hearts and minds', and intelligence led strategies against terrorism, that ultimately will be the way forward.
Even if you can do it, the cost of applying this technology to every CCTV camera in the UK, every day, all the time would be astronomical - both in terms of tech cost and manpower to validate what the tech was telling them. The number of false positives would be huge as well, it's not like a CCTV image of a person's face is as precise as, say, a finger print. There are about 400,000 CCTV cameras in/around London, and over 4 million in the UK. London Underground use facial recognition and object recognition (think abandoned rucksack) extensively, but that's in a well lit environment with well defined human traffic flows in a confined space. even sunshine or the reflection of a cloud on a windscreen could prevent someone being identified. I know this sort of tech exists, but I was of the opinion it is used retrospectively ?
And by the way, is advocating a society where everyone / anyone can be (and are) tracked by their face on CCTV a good thing ? All passport photos and driving licence photos are digitally stored now, so in theory could be applied to this technology, where it exists. And of course CCTVs can be hacked into, so that sort of capability could be used for criminal purposes too. Bit Big Brother if you ask me.
Nothing could have prevented what happened - what our security services did was mitigate the threat effectively, and fortunately the chap (or his car) wasn't strapped up with a huge bomb.
