I'm really confused in general. Because whistleblowing by its very nature is going to involve law-breaking most of the time, so your arguments are on some level implying an opposition to whistleblowing on principle.
My argument there doesn't really have anything to do with whistleblowing
per se, actually. That's a whole different kettle of fish compared to journalism and already shat on hard enough this particular situation is going to probably do sod all to its perils, which does by its nature tend to involve law breaking.
Rather the point is that journalism and journalistic protections, at the absolute least in the US, does not, has not, and by and large I have trouble conceiving a state of things where they
would (as that would be basically giving free reign to all sorts of shit, so long as a veneer of reporting was slathered over it), receive a pass for criminal behavior in pursuit of a story. It's one of the reasons reporters tend to seek sources rather than do that sort of scut work themselves -- they have protections regarding dissemination and whatnot (i.e. journalism and reporting), but the protections they have for direct acquisition and assisting in it are much, much slimmer. Particularly when it involves breaking laws.
Which is to say what's currently aimed at Assange, if it goes through, would do
bugger all to the state of journalism, even if you
do accept unquestionably that he counts as a journalist. What he's getting hit with was already something protections didn't exist for. If he were extradited, charged, and somehow (presumably someone breaks out a hyperbolic time court) sentenced before Monday,
nothing about the state of journalism in the US would have changed. Nothing. There would be no new precedent involved, no novel legal issues, just, as noted and at most, a reaffirmation that journalistic practice does not absolve you of criminal culpability. Which was just as true last week as it will be the week after whatever happens on the extradition front happens.
