There's little reason to say that "X judge lives at Y address" is equivalently deserving of protection. We might choose to protect your saying so out of an abundance of caution, to avoid a slippery slope whereby we restrict too much speech. But the idea they're equivalently valuable things to protect in their own right needs a serious defense.
Investigative journalism revealing corruption.
It might not be the address per se but it will be similarly identifying and revealing information about a persons day to day life. This information would be communicated both while reporting the story, between reporters and other sources, etc., as well as exposed in the journalistic product itself.
Or, given five seconds of thought, that was the first, obvious thing that came to mind.
I'm not talking about that - and I have no problem if judges (or anyone else) have extra bodyguards or special limousines.
I can say anything I like about the president. The same is true for these judges. The equal protection I am speaking of is not what kind of armor their car has, but what I am, and am not, allowed to say to or about them.
