"Lawyers I spoke with said that my address book — which contains my reporting sources at companies and in government — is protected under the First Amendment."
What does this even mean? Does he mean the fourth amendment? If so, lawyers would have told him "not once it leaves your phone". What do you mean by "protected"? That you can't be compelled to divulge it at all? That police need a warrant to get at it? That you can sue if someone else exposes it?
So I flipped the bozo bit. If the author plunks a meaningless but frightening sounding paragraph in the middle of an article, I just don't really put a high value on anything he has to say.
