These officers made a huge mistake when they stopped a teacher just because she refused to answer a citizenship question. Instead of respecting her rights, they escalated the situation, even denying her son a bathroom break. But moments later, they were the ones schooled on what the law really says. >> Are we crossing a border? >> No, but are you United States citizens? >> I've never been asked if I'm a citizen before when I'm traveling down the road. >> This is an immigration checkpoint, >> right? But we're not crossing a border. I'm a teacher and on the national level, we've been talking about this. Am I free to go or are you detaining me? You >> are being detained, M. >> Okay. I'm being detained on what grounds? >> It's the immigration checkpoint, ma'am. >> Oh, no. You're covering part of it. >> No, I'm in my check right here. >> Right here. >> Checkpoint authority. >> So, and it's a checkpoint and we're not actually crossing a border right now. You already illegally search my car. You have no grounds for searching my car with a dog. What happens to me if I refuse to answer your question? >> Stay here until you're answered. >> How long do you detain people while you deny them the use of a bathroom? >> It's a shame that you're not trying to be an American in my opinion. So, >> no one said that. I don't think anybody should be proud based on where they're born because it promotes nationalism which is the basis for fascism which is how people end up going to war over their national pride. >> Have you done that? >> Are we free to go? You're free to go now.
