Re: @ Naselus
"Well, you could have those in places like a browser cache or a mail folder (especially a spam folder, where they're inevitable) without ever having actually visited a porn site. "
Porn thumbnails are mysteriously absent from my own work computer - which is hopefully rather less secure than that of a minister of the crown. In fact, I can search the whole network here, and I'd be decidedly surprised to find several thousand porn thumbnails on any of the client machines. And that's just with my commercial-grade network security in place; I can only imagine what MI6 have set up for parliament.
This isn't a Hotmail account, ffs, it's a parliamentary computer on a secured network being used to work on classified documents. If it had no external spam protection or network filtering in place then that's arguably an even worse scandal, since it implies that the government network has the same security setup as a twelve year old's laptop.
As for 'if they hadn't leaked, he'd have nothing to deny'... that's more or less the entire point of whistleblowing, no? Otherwise, we're very much in the territory of 'it's only wrong if you get caught'.
Frankly, I'm not overly bothered about whether Green was sat jerking off in his office all day - it's more or less what I assume half the current cabinet are doing, since I see little evidence they're qualified for anything else - but I am concerned about the idea that IT security in the House of Commons is so lax that MPs are handing out their login credentials to any idiot on staff who asks for them. If he'd simply admitted that he was looking at porn at work, then I'd agree that he was a victim of police over-reach, but his 'someone else must've logged into my account and done it' excuse suggests he shouldn't be trusted in a position of responsibility with access to huge quantities of privileged information. And that's very much in the public interest when he's a senior public servant. At best, he's either a liar or incompetent, and at worst he's both.
