Yeah. I don't know if this lady's assessment of what happened to her is correct or not. With the available evidence, it is impossible to say whether she uttered the threats or not. I place no credence in the article, as the author is obviously biased in her favor. Clearly, those who accuse her are no freer of bias. Anyone with a recording of the event could clear the matter up completely.
This does demonstrate another benefit of carrying a recorder. If you know that you are being recorded, because you are doing the recording, then you will more consciously check your behavior. An armed society may be a polite society, but a recorder raises the bar even higher.
