And thus it has always been since 9/11. For the past 8 years it just happened that "the President" they did "whatever they want to whomever they want" under was Obama, a fact that it seems convenient to forget. Both black and white TSA agents (and yes, both male and female) at US airports have always been well known to be just as officious in equal measure. It has long happened to travellers of every colour and nationality (including white middle aged male US citizens) at every airport and every day in the USA but now people are commenting on people like Ali's son and Mem Fox as if they are being singled out subsequent to Trump's presidency. I can recall reading of celebrities whinging about their treatment by immigration people at US airports years ago. To imply that the situation now is different under Trump is complete and utter fabricated bunkum.
If there's one thing smart people have always known about travel into the USA it is that that the only thing you say to TSA agents is "Yes sir" or "Yes mam".
