This is exactly what I have been thinking. How can Armstrong not be caught when they just show up and knock on his door for a drug test at anytime when he was active in the sport of cycling. When you read about how the cycling governing body were after him because he was dominating their sport for so long and they never could find any doping going on. There were other big names that got caught. I just can't believe he was the only one that knew how to "beat the system".How many drug tests does the dude have to pass? Isnt 500 enough?
