As I said above, very different. Lawyers are held to different standards. LE are required to tell the truth in court, but can lie to the public to assist in an investigation.
There's no difference and that's not any rationale for obligating a lawyer to be truthful with the media. There's an attorney-client privilege in effect, for one thing. And pure honesty to the public might undermine the lawyer's defense strategy. Don't you suppose that LE monitors Baez's public statements?
I still don't understand the point, or the general presumption that people here are absolutely entitled to know what Baez is planning ahead of time. To steal a line from Casey, "Everyone Lies". Does the NFL football coach in your town tell the media in advance what the game plan is for the team's next game?
There are all kinds of lies. Some lies prejudice the listener, placing them in a bad position. There are innocent white lies. There are lies of necessity. It's perfectly acceptable to opine that Baez is a bad lawyer. But he's not really lying to anyone -- not in the bad sense of that word.
