Found this in the comments section of the cnn article.
Obviously you do not know how to read. The USDA report clearly states he was concluded to have used banned substances by "non analytical reasons."
In other words he passed every drug test. His guilt is being placed on hearsay evidence. And those testifying have each failed a drug test. Seven out of the eleven on the team failed. Armstrong is one of four who did not. But because the seven were found by scientific means, they are simply throwing the other four under the bus with them.
Seems this guy passed all the tests, so on what grounds will he be convicted.

Reports: Armstrong admits to Oprah he cheated during cycling career - CNN.com
Another excellent article which says that his PR did a great job to handle this. Must read.
Lance Armstrong and the cost-benefit analysis of confession | Matt Seaton | Sport | guardian.co.uk
In short, this now looks like a carefully choreographed, slow-release PR plan – likely managed by Armstrong's long-time agent Bill Stapleton – to perform a 180-degree turn on all previously held positions: belligerent denial, self-righteous indignation and bullying belittling of accusers. Instead, we have Lance Armstrong the penitent sinner: the weepy, choked-up prodigal son, who is finally coming clean and seeks redemption. As is well-established, an audience with Oprah achieves that almost instantaneously: I can see her right now, reaching out and taking his hand as he shakes with emotion and talks about the pain of living the false life we all made him lead.
And from redemption to rehabilitation. Armstrong will leverage his confession to the maximum to get his lifetime ban reduced, to four years, perhaps less. He'll be back before we know it: a slightly grizzled and more wrinkled version of himself, glad-handing and fist-bumping on the triathlon circuit, getting back to fundraising for the Livestrong Foundation, making faux-humble speeches for fat fees on the after-dinner circuit, mopping up some handy corporate sponsorships, reconnecting with his Washington power-broker contacts, and – older and wiser – maybe even running for office himself, as was once mooted.
