"...there is no suggestion anyone was to blame for Walker's crash..." unless you follow that link which says that the police suspect that speed was involved. No question that anyone not in the car was to blame is a different sentence indeed. Looking at the pictures of the scene its hard to imagine that they were driving anywhere close to the 45mph speed limit.
And later they estimate the car was going 40-45mph. http://www.nbcnews.com/entertainment/paul-walker-was-real-hero-daughter-heart-soul-his-charity-2D11683842
How about waiting until the investigation is complete before jumping to conclusions? The police comment on random shit just to comment in cases like these. For some reason nobody considers "I have no idea, we're still investigating" an appropriate answer.
