This isn't just about awareness, he hit her because of the way she looked at him. Maybe a little sneer of superiority as she walked past that bum
The problem is you can't always predict how your words or actions will be taken.
reminds me a bit of this clip http://www.youtube.com/watch?v=wkh6if8TL2U
as to the validation, well its a nasty attack but now you know what one of those techniques will look like in a real fight, also was he a uechika? or was that some streetfighting technique that he just picked up, is it a common street move. Maybe that is how the move found it's way into martial arts
I don't think this has any bearing how a techniques like this "would look in a real fight." Don't consider this to be a "real fight." I also doubt he studied uechi, or even thought about a technique.
This attack even if there was "a sneer of superiority" is an unexcusable, punk, cowardly act. I get upset at your connecting it to uechi and implying that this demonstrates anything positive- uechi or otherwise.
