Can't speak for Briana's situation and certainly none of us would be surprised if she wasn't clean, however have you guys been tested out of competition before.
I know at our team camp 2 years ago one of the athletes I was coaching got tested around 10:00am. They came to his house in Santa Barbara around 7:30am and he wasn't there, nor should he have been since his whereabouts info said he was in Orange County at a training camp. We told the tester we'd wait for him at the hotel and they took blood and urine but by then he also had several hours notice, which seems to negate the whole point and at least at the time I believe he could have just refused so we could get out and train and there would be no repercussions since USADA had messed up. He waited because it's the right thing to do, but point is the testers are not as professional as you guys would hope and think.
