Agree mostly with gareththomasnz
If you read the full transcript of the recording (which has been publicly available for over two years):
Wright become highly intoxicated.
She faked losing her phone and accused Tostee of stealing it before revealing she had it on her person the entire time.
Later she started to become violent and began throwing rocks at Tostee.
He then repeatedly and increasingly angrily asked her to leave (this was when he said "you're lucky I haven't chucked you off the balcony).
She stayed.
He then tried to physically throw her out (this is when he said "You're not taking any of your things, I'm throwing you out just as you are")
She grabbed a telescope and hit him with it.
He then pinned her to the floor and forced her to drop it.
He threw her onto the balcony, accused her of trying to kill him and said he had proof (the recording).
She begged him to let her go and she refused ("I would but you've been a bad girl")
He then locked the door, she screamed and then silence.
I understand the cops are relying on a precedent where a woman jumped out her 9th story window when her husband came at her with a knife. This case is very different though. By locking her out on they balcony Tostee removed any immediate threat of harm
All up, it seems more like he was threatening to press charges than to kill her. His actions in locking her on the balcony where definitely vindictive and malicious, but it's fairly clear that he never intended her physical harm imo.
Now you could argue that leaving a drunk, frightened and unbalanced young woman on the balcony was reckless/criminally negligent. Manslaughter maybe, but definitely not murder imo.
The judge that granted him bail said as much when she stated that the case for a murder charge was not strong and that manslaughter might be more appropriate.
Two defenders of Tostee join in short order. Tell me, so I can properly understand your posts and motivations. Are you part of some sort of Tostee defence group?
