Is it feasable that Airports that have scanners instead of Human 'observers', at airports for instance, could have the capacity to store Passport Photo's? Going through airports the human factor of visually inspecting travellers I.D, is open to abuse and flawed. If there was a 'scanner' at every airport, then retracing data such as names..photographs of individuals, could prove important at certain times..later fro instance. If Dr Elnashar could be traced to Madrid a number of months before the Bombing, as he is known to have been in the UK previous to the London Bombing, and coincedentally was known to be at North Carolina State University in 2000..(dont know if this is relevant,9'11 )is this co-incedental information, able to be retracted from photographic scanners? Is the technology here to enable 'after-event-retracing' of individuals? I would have thought an ordinary computer like scanner, would be able to do the job much better than humans? P.S Magdi Mahmoud al-Nashar is wanted in UK over links to London Bombers?: http://news.bbc.co.uk/1/hi/uk/4686089.stm In a recent interview his brother in Egypt stated that he just came over to Egypt for a holiday and was saying that he was happy in the UK and was in the process of shopping around for a new flat ?
