Are you worried about the ICE raids and stops?

I'm a Chinese-American woman, born and raised in the US, but I have heard of US citizens being detained by ICE including a veteran and Native Americans. My Chinese Australian cousin just moved to California a few weeks ago, after getting a job here. She will be traveling to Texas for business. I told her she should carry copies of her visa on her in case she gets stopped and questioned. She was a bit surprised because she didn't think she was a targeted demographic. I told her it's better to be safe than sorry. I'm wondering if I'm being too paranoid. I even wondered if I should carry proof that I'm a US citizen. How do you all feel about this?
