Top Tweets - Lance Armstrong Calls It Quits

I can't pretend to know the truth about the doping accusations against 7-time Tour de France champion Lance Armstrong.

According to the US Anti-Doping Agency, the evidence against Armstrong is overwhelming, and the cyclist is giving up the fight against the allegations to avoid the awful embarrassment of the truth.

In a statement released by Armstrong, he characterizes the entire USADA investigation as an unfair witch hunt, and says he will no longer fight the charges because "enough is enough."

When I can't decide where the truth lies in a public dispute such as this, I do the only thing I can. I turn to Twitter for perspective. And, jokes.

Turn of Phrase - New Lance Armstrong Doping Charges

"I have never doped, and, unlike many of my accusers, I have competed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one."

- From seven-time Tour de France cycling champion Lance Armstrong, who faces a fresh round of doping allegations from the U.S. Anti-Doping Agency.

Interestingly, Armstrong retired from cycling last year, but if found guilty, he could be stripped of all his previous cycling victories. The USADA accusations also prohibit Armstrong from participating in triathlons, a sport in which he currently competes.

Armstrong continues to declare his total innocence, claiming the USADA is pursuing him vengefully and spitefully.

I don't know what to believe, but I will say if you've been chasing someone for the better part of a decade (no cycling pun intended) and you haven't caught him yet, and federal prosecutors ended their two-year inquiry in February, and the guy has already retired from your sport, and there's no homicide involved...you might want to think about investing your resources in something else.
