I'll take your word for that. However, it is an important part of what W was doing in his Home. Surely, you accept that is extra-ordinary conduct on her part?
No, I don't, and neither did the Crown. At no time, never, not once, did the Prosecutor suggest he unlawfully assaulted her inside the Unit. He conceded it was probable W was unlawfully assaulting him with that metal object. That assault could easily have lead to his death or GBH. He was lawfully entitled to defend himself and neutralise her, as he did by removing her to the balcony.
Well, that is why the Expert was called. She gave evidence that she found nothing consistent with any physical injury she suffered at the hands on Tostee, but, there is not doubt he did physically 'handle' her in very restrained self defence and to prevent her being a continuing threat to him.
