There is an article from a Swedish tabloid which could be of interest [1], unfortunately only available in Swedish AFAIK. The reason this article is of interest is mainly that it shows that the Swedish prosecutors seem to be extremely reluctant to issue arrest warrants for people in other EU countries.

In summary, and I hope I do not misrepresent the article too much, a man from Sweden went on a one-day cruise to the Åland Islands. After being out partying on the ship he goes back to his cabin. On his way there he meets two musicians (temporarily) employed by the cruise company and somehow get into a fight with them. (The article is very sparse on details on how the fight started, for the record.)

Note that the fight takes place in front of a CCTV camera, and supposedly one can see on the surveillance photos one of the musicians taking charge and stomping the victim five times in the head, with full force. After briefly leaving, the musicians then returns and kicks him in the face, twice.

The article then discusses the subpar response from the security guards employed by the cruise company.

The musicians are later arrested by the Åland police, their identities checked, but are later released. According to the article they are released because the possible crime was committed in Swedish territory and they are not Finnish citizens [2]. The musicians then return home to Ireland.

However, Swedish police or prosecutors do not seem interested in investigating this case. When pressed on why the prosecutor does not issue an arrest warrant for the men, their identities and whereabouts are supposedly known, he responds by saying that the Swedish prosecutor authority cannot go chasing people all across Europe and they only issue arrest warrants for very serious crimes, like murder.

To summarize the timeline. These events took place in October 2009, if I understand correctly. The Assange case started in August 2010. The news paper article was published in late October 2010.

So, according to this tabloid story, this is an open and shut case for a fairly serious crime, and still the prosecutor authority cannot even be arsed to issue an arrest warrant. At the same time they keep Assange locked in an embassy far longer than he could even be sentenced to for the crime he is accused of commiting. And the Assange case certainly seems much more flimsy, I'm not even sure what he is accused of, exactly. But it certainly seems to boil down to some he-said, she-said situation that will be completely impossible to get to the bottom of.

IIRC he can at most be sentenced to 4 years in prison for the sex crimes he is accused of in Sweden. But in practice he will be released after serving two thirds of this sentence, so he would spend at most 2.6 years in prison. Note also that it seems to me EXTREMLY unlikely that he would recieve a sentence of 4 years, at the very most 2 years but 1 year seems more probable. So if he just left the embassy, went to Sweden and lost the case, then he would most likely be a free man after just 8 months. So his actions certainly seem to indicate that he fears something more than just being found guilty of "less-severe rape". (Sounds a bit weird but is the crime he is accused of IIUC.)

Just to reiterate, he has spent close to 7 years in the embassy for a crime which he would quite likely serve 8 months in prison for.

With the caveat that I am now a lawyer, and whatnot. Quite possibly I've screwed something up in this last part of the analysis.

Edit: To further clarify the point, I guess it is that there is maybe not anything wrong with how he is being treated if one looks at this case in isolation. But when one combines this with how other cases seem to be handled, as well as considering proportionality, things are less clear.
