Agree on all points. 'offering their sympathies' is also complete BS. We know why they are there. Not to mention this is a working farm and they can and often do refuse to have anyone enter for infection control reasons amongst others.I didn't see the weapon waved--the grip was changed once--but I agree that showing it was intended as threatening. I think it was a measured performance, that Josie knew exactly what she could legally do and she went right up to that line and didn't cross it.
I don't own a gun but I think if it were me under the circumstances I might also do something that would give them the distinct impression they are not welcome as they obviously haven't got the message previously. I might release the hounds.
Also pretty sure there are some code of ethics around entering properties for journalists. Not to mention health and safety and a duty of care.
