The Texas Parks & Wildlife Department clarifies the issue of who was at fault.

[T]he Texas Parks and Wildlife Department said it will classify the Saturday shooting as an error in judgment by Cheney, said Steve Hall, education director for the department. Members of the hunting party have blamed Whittington for not announcing his location to the others.

While medical experts question Katharine Armstrong’s claim that Harry Whittington was 30 yards away from Cheney when he was shot.

The account given yesterday by doctors caring for the Texas lawyer accidentally shot by Vice President Dick Cheney last weekend raises serious questions about how and when a pellet entered his heart and what tests were done to establish where the pellet was lodged, doctors not connected with his case said.

Although the public was told for the first time yesterday that a shotgun pellet from a hunting accident had lodged in the lawyer’s heart, one of his doctors said that “we knew that he had some birdshot very close to the heart from the get-go,” but not its precise location.

Earlier accounts described as minor the pellet wounds that the lawyer, Harry M. Whittington, suffered in the face, neck, chest and ribs.

Dr. O. Wayne Isom, the chairman of heart and chest surgery at Weill Cornell Medical College, said it was unlikely that a pellet would migrate to the heart through the bloodstream, as some have assumed from the account of the Texas doctors.

The reason, Dr. Isom said, is that the pellet would have to enter a vein, travel to and through the lung vessels that go to the heart, and then lodge in heart tissue, not in one of its chambers. The pellets were approximately five millimeters, about the size of a BB, and larger than most blood vessels, said Dr. David Blanchard, director of emergency services at the hospital.

A more likely explanation, Dr. Isom said, is that the pellet lodged in or touched the heart when Mr. Whittington was shot.
