The reality is - it doesn't matter. The fact that they have had as many false positives as they have and the way they treat people in general causes it to have rippling effects even for people who are legally here, or are considering legally immigrating.

The risk and level of publicity is just too high for many people to even consider, especially people already intelligent/capable enough to immigrate anywhere else that doesn't have these issues or stay in their own country.

No, all of the specific cases I heard about were Chinese people that were naturalized citizens (some for decades) who were cuffed and detained for a few hours before being released. As others have said it doesn't really matter, though. It's the sentiment that counts.

Even if you're not likely to be deported from a foreign country, you wouldn't want to face frequent gang intimidation tactics, would you? Simply feeling threatened isn't fun, even if nothing truly terrible will happen to you (not to speak of the real risk in being detained regardless).

Sometimes, often times no. They have detained multiple US citizens.

Who cares when you get a bonus per person either way?
