"If you antagonize one class of people, you reduce their willingness, as a group, to cooperate with authorities." The question is whether this effect is stronger or weaker than the gains you get from profiling. The middle solution: Anti-profiling. It's not about going after certain groups, it's about ignoring certain groups that are harmless. We don't need to focus on: -70-year-old British grandmas -4-year-old children -Chinese women -etc. Obviously this doesn't preclude someone slipping something into their bag without their knowledge, so bags would still have to be checked. But at the end of the day, there's a lot of simple things you could do to make the whole process faster and easier for everyone, including 23-year-old Arab men with congenital overactive sweat glands.
