By one means or another he acquired, seemingly legally, a large quantity of documents which would expose the detail of what went on in diplomatic circles, though again it is what diplomats always knew and the rest always suspected, there has been just a small possibility that it could have been used to alter the system to make it a bit more honest.
His first problem came with his lack of concern for some of the small people who would be exposed as informants in dangerous parts of the world. Next he decides to take advantage of his popularity to get his end away, well who wouldn't, I definitely would but there are not just honey traps set up by the CIA, but gold diggers, blackmailers, people with axes to grind and media whores out there who would look on Assange as a meal ticket. If you going to put your self in a delicate situation play it a little cautious you have a brand to protect Julian but he didn't.
Exactly what, if anything he is guilty of being a matter for the courts, his own admissions make that clear there is a case to answer but there are some quiet obvious answers to the questions which put him on the right side of the law, I know of at least one person who liked the idea of being woken by an orgasm, though I would have insisted on having it in writing, if it was someone I'd only just met or I wouldn't go for it.
He is not going to be accepted as a diplomat by the UK whatever Ecuador does, so as soon as he leaves he will be arrested, if he doesn't leave time in a Swedish gaol may seem preferable. The only thing he is doing now is making himself look increasingly foolish and destroying whatever Kudos he had earned.
Sooner or later he will just be a fool he started off with lofty ambitions for what he could do, and while he may never have been able to achieve them he has squandered what difference he could make, at every turn he has acted to make himself look petty. I doubt the Swedes would give him to the US, even if they did it would be with a no execution agreement. So he either has to face life in the Ecuadorian embassy or walk out and take the chances with the Swedes, and I think the chances are in his favour, but the more time he spends in Ecuador the more guilty he looks and the more time he like to face for being in breach of his bail conditions.
The way he is acting reminds me of a minor UK pressure group know as the "Freemen of the Land", who are to say the least deluded.
