Well, he sure didn't make that the priority of the discussion which for intents and purposes is far more important. Heck, he even says "But the image that's more clear to me is his gun." I mean, can you imagine what Bruce would have said if the murderer used a pencil?
"But the image that's more clear to me is his pencil. A #2 half a foot long lead based pencil...with "study hard!' written on one of the sides and the eraser gone and the metal eraser holder cramped together. There were three bite marks on it, near the eraser, on the #2 label and near the tip. The pencil was yellow with a metal eraser holder. It drew three dots. Pencils are NOT tools. They were created for no other purpose than to murder human beings!"
