White guy 10PM Saturday night on fisherman's wharf eyes-glued to the iPhone and they wonder what the 'motive' is for the slaying?
How frigging duplicitous are these people?
Being white, distracted and in a tourist spot at 10pm on a Saturday nite is NOT a motive.
A motive would be that the perp wanted to rob him (which obviously didn't happen), or was a psycho killer (possibly one who hates Pokemon?), or someone who had a personal beef with him, or some leftist anti-white political whacko wanting to kill whitey.
True, it's not wise to walk around in public completely distracted, but in and of itself, the most you can say is that doing so presents an opportunity for criminal attack. But in and of itself it cannot be a motive.
