“KING: Why did they have to take [a portion of your skull] off?

B. WOODRUFF: Because what happens when you get hit really — on the side like that, which is called a traumatic brain injury, your brain starts to swell. And if you leave the brain, the skull closed around it, then there can be damage terribly. Even possibly you could die. So you’ve got to get part of that off so that it expands and goes outside of your head.

KING: Do they tell you what they were doing?”

Yes Larry, yes they did.
