The TSA is investigating an incident where an agent at Los Angeles International Airport allegedly publicly shamed a teenager about the clothes she was wearing onto a plane. Blogger Mark Frauenfelder says his 15-year-old daughter was confronted by the agent during a pre-flight security check, where the agent allegedly said "You're only 15. Cover yourself." in front of other passengers. The teen was traveling with some high school students for a college tour. TSA officials say they are taking the complaint seriously and thoroughly reviewing the alleged incident.
