As for Assange. First, he should face the charges in Sweden. Just like I would have to or anyone else.
His "journalism" looks like information warfare to me, and I detect a significant anti US bias. Frequently I see this bias in his supporters too. I think some of what his organization has done is good, but it is a mixed bag and some of it has endangered US military ops. Overall I would say he commits information warfare primarily against the USA while hiding behind the shield of "Journalism".

Yes, that is what we call enforcing our laws. Those laws are there for a very good reason. Joe Private simply cannot make the determination as to what should be secret and what should be released to the press. If Joe Private feels something should not be classified, he does have avenues to actually address that which will provide him protection from recrimination.
