What are you guys talking about?
If the police are made aware of a crime, and if the state's attorney can show the judge that valuable evidence is in a given residence and on computers, then a search warrant can be issued to secure that evidence. No notice is given, of course, because such evidence might go missing if notice was served prior to the search.
Journalists are not immune to search warrants. They are immune to certain types of searches under _very_ specific rules in order to protect them and their sources from undue pressure.
However, when it's clear that a journalist HAS committed a crime, and in fact has published their crime, a judge is more likely than not going to issue a search warrant.
Just because they are journalists does not mean that they are immune from prosecution - in that case I might as well become a journalist, and break into Apple's labs, then when I'm caught say, "Oh, hey, I'm a journalist so you can't, you know, actually prosecute me for this."
There are some very narrow allowances made for illegal activities, such as in whistleblower cases (ie, journalists handling - but not paying for - corporate trade secrets, IP, etc) where there is a common good that will be served by making these things public.
But in this case, neither of these journalistic protections apply, even if you claim gawker/gizmodo have journalist rights. Firstly, they are committing a crime. Period. Second, there is no common public good served by disclosing this information.
So yes, of course they are going to cry foul when they are searched and _claim_ that the search is illegal. And of course the various organizations that support journalism are going to go on record that this is a bad thing. But that doesn't make either of them right.
The real worry that these organizations have is that this case may actually tighten down the standards journalists can now work under. If anything they should be angry with Gawker for forcing this open for legal scrutiny again.
But it doesn't matter.
At the end of the day, they broke the law, and they will pay the price. They are not immune to search and seizure and prosecution from criminal acts.
