Update: The judge is admitting it's him, so my post is moot. I still find the daughter's reasons for releasing it to be shady - she got fed up with a series of "small disputes" with her father, she threatened him with the video before posting, she chose to wait seven years to "distance herself from the consequences." None of this sits right with me. Disfunction in every part of that family.... And none of her reasons are related to "healing" as your SWH would suggest. I do actually understand that the time to heal from something like that is decades - however, from her own mouth, she didn't do it as part of healing, and I'm not sure how publicly shaming her father would be a part of the healing process. Talking with him, confronting HIM with it, or even releasing it to the court system to evaluate his fittness for his position, but releasing it on the internet? Not healing - revenge.
Original: Not suggesting she's lying, but right now they can't identify any of the people on the video. It's this girl's word against her father's. It's entirely possible, though.
I find it odd that she videotaped it that long ago and just held onto it. If the beatings were that savage and she had proof at the time, why not turn him in then?
Edit: I have not actually watched the video. I choose not to expose myself to those types of images, so I don't know how clear the video was. The news reports I read about it mentioned that police cannot identify anyone on the video conclusively.
