The article posted said 170 citizens over 9 nomths. Thats about 15 people a month (if you believe they are giving an honest account, which i seriously doubt).
If you are confronted by ICE then just prove you are a citizen. I would happily do so. It is a minor inconvenience at worst and i don't agree with the way you are framing the argument.
Many of those 170 probably tried to interfere with an investigation. I doubt they are accurately portraying the whole story.
I'm asking sincerely - how do you prove you're a citizen? What do you carry around with you that trivializes this?
