From the article:
The full-body scanners at airports across the country frequently give false alarms for Afros, braids, twists and other hairstyles popular among black women.
This has been a thing since it all started. My coworkers at my old job always got pulled too because of black hair styles.
I have all the sympathy in the world because trans folks get pulled, too. It wasn’t until I had top surgery that they stopped thinking I was smuggling something in. It was a small window into the issue that they have to face every time they flew.
I think the whole thing is a ridiculous exercise in bag policy and technology.
