Don't be afraid of standing up to these morons. Be sarcastic, loud, make a scene, within boundaries of course, so they can't tackle and cuff you. Would I let those assholes grope my family. No way. So do I stand at an impasse all day or simply not take the flight. Other people are waiting! Long lines, let's go! Maybe I loudly ask the why they want to feel up my kid. Everyone has a cell phone camera. Let's see how far they go.
