Why believe a liar now?

I was shocked and stunned to hear a national radio program discussing – with some seriousness – if allegations made by Floyd Landis might tarnish the reputation of Lance Armstrong.
Now, one might be forgiven for not knowing who Landis is, but you’d have to have been living under a rock to not know that Armstrong, seven-time winner of the Tour de France, is the world’s most identifiable cyclist.
In a sport mired in more drugs than any other, Armstrong has yet to fail any test, and is largely accepted as the most tested athlete in all of sport.
OK, so here’s Landis, a former team-mate, who earlier this month decided that after years of denying use of steroids changed his tune.
So now Landis is admitting he was, all this time, doped to the gills like every other drug loser in the sport.
Hardly a surprise.
Most of those who protest a failed drug test eventually come clean.
But for years, Landis cried innocent, even raising $1 million in public money, bilking donors who believed his tale that the French authorities were out to get the good-old-Amurican boy.
So he was lying then, but now he’s coming clean?
It’s hard to suggest that Landis is suddenly being truthful when he points his fingers at Armstrong.
Meanwhile, here’s Armstrong, the man who has yet to fail a drug test in his career, saying as he always has, that he’s clean and will always be that way.
Landis is a liar and cheat. That can safely be said, because the trail of evidence is clear: he said he didn't take drugs, and now he admits he did, so he lied. He cheated - not only by racing while doped, but also when he sought donations to mount a legal defense against drug use findings he now admits were true - so he's also cheated innocent people of their hard-earned loot. (We won't even mention the money he made writing a book about his ordeal.)
Landis should be banned from cycling for life, as an example to the clowns who continue to think they can avoid being caught.
I’m not sure what I find more distressful: that Landis is clearly spinning another fanciful yarn, or that one of my media peers was dumb enough to buy the guy’s story long enough to give it air time.
