His TSA story is more likely fiction. Is he saying that there are "TSA" in London? And in either case I've never seen the TSA select people "randomly" by name alone (in fact they do their profiling based on appearance, not name, which is arguably even more insidious). Even if they DID select by name, how would he, a selectee know the names of everyone else selected at the same time? The whole story makes no sense and sounds made up (by someone who's never travelled or been randomly selected no less).
I've been randomly selected a handful of times, but they don't know my name when they do so.
