Thomas, I presume you mean well, wish to be truthful, and never want to present as fact that which is demonstrably false. The link to the video that you provided was used in a "news" story that did include just a kernel of truth. A young boy was indeed detained at IAD Dulles Airport.
The photo of a handcuffed (upper arms) boy was NOT the boy at Dulles. He is dressed differently and looks very different from THAT boy.
One of the world's best debunkers of misinformation, disinformation and outright lies is SNOPES.com. See: http://www.snopes.com/small-child-handcuffed-at-dulles/
Snopes says: "However, we traced the image back to an August 2015 controversy in Kentucky involving sheriff’s deputies handcuffing young students with learning disabilities."
Another excellent video debunking "your" video and news item is found at VERIFY: http://www.wusa9.com/news/local/verify- ... /395580032
This is a production of WUSA 9, which is a legitimate journalistic TV news source in Washington, D.C.
Before you post such outrageous misinformation, you might at least do a Google or Yahoo search to see whether your garbage UK "media" site can be confirmed by legitimate news sources. Here are the results of a simple search:https://search.yahoo.com/yhs/search?p=B ... mp=yhs-001
None of the above is to deny that a young traveler was detained, and probably for an egregious amount of time, at Dulles Airport. I doubt that all of the circumstances are revealed by the reportage in the search results.
Yours truly, in the hope of future honesty,
Facts are fragile things. Treat them with care. Sources are important. Alternative facts do not exist.
