You ever express any opinion besides the subject at hand in an email? You can get banned on this board for cracking a joke about a political party on the SSF; can you imagine what the press would do with any opinion someone voices in a private email that has nothing to do with the subject in question - perhaps a comment about a person you know or a comment about a politician that you wouldn't share publicly - something to the effect of "yeah, I think that guy is a donkey"? It's not "hiding something". It's keeping private communications private. They have zero constitutional or legal right to make those emails public. The emails has ZERO to do with committing or covering up a crime; consultation of this kind may and should be privelaged.
