While a recording of the unfortunate crash that killed Paul Walker and Roger Rodas might give investigators some idea of what happened and end the rampant speculation, the video circulating now mostly serves to feed the media's need for fresh images. But if you stick around after the crash you'll see something noteworthy.
Having ruled out street racing — a storyline probably fueled by Walker's film career more than anything — we're left to wonder if a mechanical or human error was behind the crash. Not that knowing this would change much in the short term. Two people are dead, many people are grieving.
