The killing of Trayvon Martin by George Zimmerman — the case where nothing makes sense, nothing — gained greater clarity in the last couple days. The story put forth by the Sanford Police Department and by Zimmerman “friend” Joe Oliver is starting to crumble.

Let’s go to the videotape.

The leaked police report of Zimmerman’s account of what happened the early evening of Feb. 26 said that Trayvon punched the neighborhood watch volunteer in the face. Trayvon then “got on top of him and began slamming his head into the sidewalk,” Zimmerman told police. “Zimmerman then shot Trayvon once in the chest at very close range, according to authorities. When police arrived less than two minutes later, Zimmerman was bleeding from the nose, had a swollen lip and had bloody lacerations to the back of his head.”

But a copy of the video of Zimmerman’s arrival at the police department aired by ABC News on Wednesday shows something different.

Look how tidy Zimmerman looks. Where is the blood, either his or Trayvon’s? Where’s the swollen lip, the bloody lacerations to the back of his head? Where are the bandages? Where are the signs of struggle? For a man who shot and killed an unarmed teenager, who was described as screaming for help and fighting for his life, Zimmerman looks awfully presentable.
