There needs to be actual evidence - not just testimony. Even to get people on perjury, they're going to have to come up with actual evidence to prove the lies, right? I mean, at some point they have to prove who is telling the truth and who isn't: they shouldn't be able to use testimony from one guy saying, "I saw him dope," to prove the other guy was lying when he said he didn't dope. He said, she said.
But overall, what the general public, and even the sports fan, wants is actual rule violations proven by the testing authorities. Failed tests. Without that, the whole thing is just a lot of talk and the defense of, "How come he never failed a test," trumps all.
That's why the only claim in Landis' statements that really counts is the one of the coverup regarding the positive test at Tour de Suisse. Landis says 2002 when Lance didn't even ride it though, which wipes out trust in the diaries Landis claims he kept at the time because if they were truly diaries from that time, he'd have the date right and only could have gotten wrong because he's writing stuff down now many years later. But regardless, if actual proof of this test result and a payoff can be shown, it would mean something.
Here's the deal: most people believe some version of, "It's not cheating if you don't get caught." It's because of the way the West has set up their religions and governments and thus the overall culture. Rules have been created and then penalties for violating those rules. People don't spend any time talking about the fact that the rule should be followed because it leads to a better personal or societal outcome. They just say that one should follow the rule because if he doesn't the penalty is severe (he's going to hell, he's going to jail, or he's paying a fine). It's just a contract.
And thus all we agree to as citizens is not so much that we'll follow the rule, but that we agree that if we break the rule, and are caught in such a way that seems fair and square and doesn't violate our human rights, then we must suffer the penalty.
So we all go around living our lives breaking the "rules" of business or relationships or law every single day: and as long as we are prepared to pay the penalties if caught, we consider ourselves to still be righteous and living by the overall concept of the rules.
Accusations from neighbors or coworkers and the like don't count. Even self confessions are less than satisfying. People just don't see it as a true rule violation until the body responsible for enforcing those rules actually catches the violator. That's when the rule was actually broken and the penalty must be paid.
But if one was legitimately caught and then tried to bribe their way out of it or used their influence to get out of paying the penalty that we'd have to pay if we were caught, then we get upset. So that "cover up" allegation is the one and only allegation that the public is likely to give a **** about.
