Seems highly unlikely to ever work, but why assume the technology is evil? If you could create a system that had a high accuracy of detecting terrorists, then that would be a good system, not an evil one.

I get your point that a system that claims to detect terrorists but only really detected Arabic people would be an evil one - but you're automatically calling the terrorist system evil without knowing if it really does detect terrorists or not.

As an extra hypothetical question, do you feel a system that could detect people who were really just about to commit terrorist attacks as good or evil? At a conceptual level, assume the system somehow scanned brain waves or some other truly difficult method.

Occam's razor. They are not 'scanning brain waves or some truly difficult method'. Not in this reality. You know it too. I didn't even have to suggest they built an Arab detector for you to bring it up ;)

I don't care about that hypothetical. Save it for your sci fi screenplay.
