Homicide or Accident in Tony Stewart’s NASCAR Scandal?

Homicide or Accident in Tony Stewart’s NASCAR Scandal? - The Daily Beast:
Three-time champ Tony Stewart is reviled—and beloved—for his take-no-prisoners, borderline-unhinged attitude. But we may never know whether he hit Kevin Ward deliberately.

....The caution flag came out, but an irate Ward, instead of getting back in his car and getting it to safety, headed toward the center of the track, jabbing his finger and presumably looking to challenge Stewart. After nearly being hit by the two preceding vehicles, Ward was clipped by the back wheel of Stewart’s car and dragged and sent flying into the air. Forty-five minutes later, he was dead.

.....The question being asked now is whether there was any intent on Stewart’s part. In the video above, it appears that right before he collided with Ward, Stewart gunned his engine, causing the car to swerve or at least fishtail.

There may be a number of reasons for such a move beyond pure malice.
