The video evidence does not show that and while you keep insisting it does then I no longer wish to carry this on
Use your eyes my friend.
But whether or not it does makes no difference to my view on the matter - his actions were unjustified and unnecessary (regardless of whether he grabs her throat or not) to my mind he was angry, out of control, and very likely drunk.
Why does this issue bother you so much - does it make a difference to your view, in other words - grabs her throat = wrong; doesn't grab her throat = OK
Is that what all this is about from your perspective?
