From what I read here, it seems that profiling at Ben Gurion results in 3% being subjected to more stringent searches. I suspect that the same profiling at a major international hub would result in a much higher percentage, since the people who travel through Ben Gurion are a more biased sample of the world's population. The advantage gained would then be limited.
In essence, you are looking for people very different from "the average passenger" at your airport or for your airline. That's much easier for a specialist airport/carrier like Ben Gurion or El Al than it is for an international hub or carrier like BA, where the range of passengers is much more diverse.
