I am on side with CF, but @Felix125 is correct.
The police have a duty to investigate and if CF is to be believed, they began demanding to speak to her urgently this week which prompted her to spiral.
It is reasonable and proportionate to arrest someone to prevent a crime or if they are in the process of committing it.
It can be reasonably inferred that CF’s alleged crimes, remembering innocent until proven guilty, were not of a violent nature. CF does not seem the type to put in someone’s windows, and I cannot see her visiting anyone’s property to leave notes or objects.
What then, was CF doing? She was fervently and imprudently posting in what appeared to the impartial observer, an agitated state.
What had caused CF to become so agitated? She said that the police rang her on her birthday, wanting to interview her over new allegations that had occurred subsequent to her arrest. She also then received a welfare check.
The complainant must have perceived that her online behaviour was posing some risk to their safety. CF needed to be arrested to prevent her from continuing to commit online crimes that harmed the victim.
Lisa Townsend is coming out in favour of the police because they may have acted procedurally correctly.
That should not imply agreement with what has happened to CF or that it is just. My suspicion is that the victim claimed that CF's posts were an imminent threat to life.
CF’s Twitter feed made reference to 3 policemen and also a policewoman who would have been needed to perform the requisite searches. This makes more sense operationally.
My take is that CF is the victim of narcissistic abuse and needs to seek an expert trauma-informed professional.
The claims about the blog are wild, and the screenshots produced on CF’s Twitter feed are worrisome.
I searched on the Antipodean registry for some background on the blog to contextualise and authenticate CF's claims. Their archivists have missed a beat.
I then checked the Wayback machine and archive today (archive.ph) for the URL cited by Farrow. The results are astonishing.
