Februs:
Talk of 'blackmail' and 'playing up to the camera' is all pure speculation. Having the shit beaten out of her, however, is not, as we can all see it with our own eyes and the state of mind it was carried out in. Not only that, but the 'judge' (I use the term loosely) isn't remotely contrite about what he did to her and clearly sees no wrong in it. Also, referring to her as a '16 year old young woman" who had "partial control of the situation" is totally bogus and in my mind a throughly perverse way to look at things, unless of course one is merely playing devil's advocate for some unknown reason.
Well, the 'playing to the camera' issue is purely speculative (AFAIK), but the local news reporting is treating the 'blackmail' threat as an admitted fact--and it neatly explains why the young lady waited seven years before releasing the recording. (I could understand her waiting until she was old enough to be legally beyond her father's ability to retaliate against her, but that presumably wouldn't have taken seven years.)
I don't believe that a teenager being spanked over clothing with a belt is all that uncommon even today, at least in the American South (notably Texas), but the guy certainly seemed to be out of control emotionally while he was strapping his daughter--it seemed as though he might be about to escalate into hitting her in the face or somewhere else (other than her posterior), although based on the video he didn't do so.
The father being a local judge doesn't surprise me all that much, AFAIC the Lone Star State has plenty of strange-acting judges serving in its small towns... --C.K.
