Most of the people involved in the protests and riots, as far as I can tell, are not residents of East Oakland. IMO, these are professional protesters that came from Berkeley or across the Bay Bridge from SF.
As far as the shooting, this is the second time within hours that something like this happened. The other event happened in an exclusive suburb of Houston, Texas called Bellaire (if you've been to Houston it is South of the Galleria off of I-610), where a 23 year old black male was on his way home when he was pulled over in front of his house because the cops suspected his vehicle to be stolen. The cops shot the unarmed man in the back in his own driveway. Having lived in Houston for a while, it is a well known fact that when passing through Bellaire, you don't mess around.
