If you flout the law you are no position to complain about paying the penalty. So far he is paying the penalty for breaking UK law, viz. skipping bail. However, as he has done this once he will not get bail a second time, while the extradition proceedings are in progress. So he will be in custody while this happens. That is entirely his fault.
Sometimes, you have to wonder though. There are a lot of people who flout the law. They might jump bail or fail to appear for their court date. Of course, warrants are issued for their arrest, but unless they're truly notorious or dangerous, they're not going to launch a massive international manhunt. Most of them probably just end up in a stack of files on someone's desk, while there's no real strong effort to actively pursue someone. It's a question of priorities, and so it's a fair question to ask what makes one case of flouting the law a higher priority than another case.
This isn't as much about Assange or his actions, as much as it's about the reaction of certain governments to him and his actions.
I think burglary is a more serious crime, and yet, the government doesn't do near enough to solve all the burglary cases out there. And yet, they all too often waste time and resources on silly stuff. This is the question that should be asked: Where are their priorities? What are they so worked up about this guy Assange for?
I'm intrigued though. If he is extradited, do you think he could not get a fair trial in the USA? If not, why not? Do you think the current laws protecting government secrets are unfair? Or do you think the US legal system is corrupt? It would be a jury trial, I presume.
I think it largely depends on how the case is handled. With the amount of attention this case is getting, there's a lot of light on it in which all the players will have to at least appear to be on the up and up. They don't want to have another botch like the O.J. case.
As far as I know (although I could be wrong), Assange never actually worked for the US government or signed any oath to not reveal classified information. So, this is quite different than US military or government employees going bad and giving/selling secrets to the enemy. This is more in the realm of aggressive investigative journalism for which one can find some sympathy in the US, from both the left and the right.
This is why they're going to have to handle this case rather delicately.
