I suggest you do some homework. There are many people in Gitmo still to this day who are innocent; a few reporters I can think of, one is still in there, I heard about him months ago. As for high profile, in the USA the media is inept at best - we barely get coverage on Assange and only probably because of the attention he gets from the internet. In other countries they made other victims get a higher profile (especially if it's one of their innocent victims-- Canada even payed for damages to one of their own for their complacency, it got coverage there.) Another issue is the other innocents are not extremely political and controversial; they are much more innocent and were/are not actively political, like most normal people are.
Due process in the USA is broken, if you have not noticed. It's much more hit or miss. Assange is clearly a flight risk, he'd be in jail from day 1 until his trial YEARS later and be prevented from doing his day job-- which is keeping his tiny organization going and funding the lawyers. The case will be bogus if they can't invent something to stick because they want to make an example out of him; they have the power to mess you up good without breaking any laws. Today they can bend the laws or break them without much trouble; it's unlikely you end up vindicated let alone having them punished for their actual legal infractions after a decade of court time.
You must have noticed the politicians and government lawyers mentioning severe terms and references to ancient laws that don't reasonably apply... but technically could apply if you have the warped reasoning of a lawyer or politician. They've been doing it on many other fronts in the name of security... You did hear them justifying the NSA stuff, no?
