A video that shows a Transportation Security Administration officer patting down a teenage boy during a security check is being widely circulated after the boy’s “livid” mother posted the footage on Facebook over the weekend following what she calls a “horrifying” experience at a Texas airport. Jennifer Williamson said in the post that she was “livid” with the TSA for detaining her young son, who has a sensory disorder, for “well over an hour” at Dallas-Fort Worth International Airport on Sunday and subjecting him to a physical screening. “We have been through hell this morning,” she wrote.
