Not entirely clear but it seems the WTMD didn't alarm but a wand did.
Allred also indicated that while the first piercing was removed easily, the second was not, and a pair of pliers was required. At the same time, while she was behind cover, Hamlin could hear a growing number of male TSA agents snickering outside.
Gotta love those professionals !
