IIRC from an interview of Sgt. Mark Francis, the WA State Patrol information officer, that didn't air (it was recorded right next to me, so I heard every word), the shooter was described as "Hispanic" by witnesses (of which there were many). I don't think it was profiling.
Also, of note, the long gun he used sure doesn't look like one of those nasty "Assault Rifles" that all the anti's are so fervently attempting to outlaw. Heck! Maybe it was a .22! I dunno! But it sure doesn't look like one of those nasty "Assault Rifles!" The scenario more describes someone with serious mental problems whom the system failed...
