Last I heard, the story was that they stood in the hallway outside of the room where this meeting was taking place, and recorded it from there.

No different from someone parking outside your house and recording you with a shotgun long distance microphone:

Just because it is possible for someone to record you without your knowledge, doesn't mean that they should be able to do so.

Absolutely correct - Huge difference from being a known participant in a conversation and an eavesdropper - whether through device or not. These guys were outside the room - there was an expectation of privacy.

If O’Keefe can be a participant in a conversation and get the other folks to say stupid things, fine with me - he should have every right to record what he will later try to say happened - the recording an objective record. But neither he nor anyone should surreptitiously record other peoples private conversations - bad as they might be.
