Especially would think someone with those kinds of views would be aware of the rather well publicised sordid history of UK police with infiltrating animal rights groups and been more cautious. Unless she was an undercover cop out fishing (I don't think it's likely, but who knows).
This was around 15 years ago, so maybe before the big recent stories about undercover-cops fathering children with their marks and vanishing etc.
I got the impression this lady I met was a little un-hinged / manic. Although more than capable of causing harassment to those unlucky to be in her path.
