Er....I meant what PROOF is there that she was raped?
You sound like Douglas Brinkley, who keeps arguing that the eye witness statements of the Swift Boat Veterans for Truth are not evidence. Not only are Kobe's accuser's statements evidence of rape, Kobe's contradictory statements are as well. Note that (a) he was denying ever having sex with her until after the police told him they had semen and pubic hair samples from her exam, and (b) he was asking if there was any way he could settle the matter before he was even charged with anything. That's strong evidence of consciousness of guilt. The physical evidence (blood, semen, pubic hair, etc.) is also strong evidence of his guilt.
Perhaps there was little chance that a jury would find him guilty beyond a reasonable doubt, but as with O.J., that doesn't mean there was no convincing evidence of his guilt.
