You seem to have some kind of strange mental block. You seem to think it is reasonable to approach an athlete for testing while the athlete is attending a White House event. Do you actually think the Secret Service is going to allow a USADA tester access to the White House? You think USADA will be able to get one of their testers on the White House guest list for that event?
Now let's think about the LAX scenario. Let's say Ms. Rollins did exit the secure area to allow the testers to test her. They would have undoubtedly performed the tests in one of the public restrooms. Gee, the Homeland Security personnel would have observed Ms. Rollins leaving the secure area, to go into a restroom with a couple of strangers who suddenly show up. What are the odds the TSA agents would have entered the restroom to see what was going on? Yeah, really great, having TSA follow you into a restroom to find someone drawing blood from you. LOL!!! Of course, the real reason she didn't exit the secure area is she needed to catch her flight to a major competition.
The public event in Florida is similar in nature.
These incidents show the USADA protocol is poorly conceived. It doesn't take a rocket scientist to figure out these kinds of scenarios.
Hopefully this wasn't a case of a USADA tester with a crush on Ms. Rollins, who was spurned for a date then decided to cause problems for her.
