There is a protocol to how this is done, and the testers carry specific identification to make it obvious and clear that they are who they say they are. Based on Lance's account, this was not the case. Since there are nutjobs all over the world, he was 100% right to check this out. And it appers he has witnesses, not the least of which was Bruyneel.
There's nothing he could do in 20 minutes in a shower to alter the results of a test.
Good Lord this is stupid.
BTW...this is the same level of professionalism exhibited by the people that handled Landis' samples.
BTWII...it's really fun to urinate in front of a tester. Especially if you are dehydrated.
