The goal of racial profiling is often to stop crime or prevent acts of terror. Of course, racial profiling does not meet that goal. Had it met that goal, it would be used still (well formally accepted anyway).
Mathematically you can prove how racial profiling also doesn't work. Here is a paper that talks about that

In term of terror, America's ally Israel which faces the most Arab terror does not racially profile. Many Israelis are of different races and thus it would be difficult first of all. Second of all, when you profile then someone will try and beat it by sending in someone that doesn't match the profile - a blonde woman to take a plane hostage for example.
