Pedophiles come in all shapes and sizes and work for all types of organizations. If you think they aren't in the TSA you're an idiot. If you wouldn't stand for this type of conduct toward your own children, why are you willing to ignore it when it's someone else's kid that this happened to? There are laws against inappropriate touching of a minor, it's time they were enforced.
If law enforcement doesn't step in, some angry parent will and then the wrong person will be going to jail.
