You do not need a degree in electronic engineering to use the Unix grep command, which is all you need to check if the IP addresses in list A (the alleged buyers) appear in list B (the Visa merchant terminal log). Further, I fail to see how this changes anything about the 54,348 stolen credit cards; we even know which company they were stolen from (Levenger, Inc.) and that they were stolen from their MS Access database.
Further, it is something of an IT industry tradition that not everybody who knows anything about computers has a "Computer Engineer By Royal Appointment" coat-of-arms; we think this is something akin to freedom. Hell, I've got an MSc in International Relations, and so has the CEO of British Telecom.
I'm not at all surprised to see this bit of the story:
'It is critical that those who serve as expert witnesses are credible on an ethical basis and do not have any alternative agendas which may affect their independent status,' said Jim Gamble, chief executive of the Child Exploitation and Online Protection Centre, which brought the case against Bates.
Indeed, indeed. How's the Forest Gate case coming on, fella?
