Part of the answer is this: Profiling should be used to let some people past the security checkpoints who are obviously not terrorists. There are many people who are obviously not terrorists, you could just take one look at my grandma, and maybe speak with her for 20 seconds to realize that she should be sent right on through the security checkpoint. This is not to say that you can spot a terrorist on sight, but you can spot some people who are not terrorists.
If the processes currently in place would single out my grandma as a potential threat, the processes are broken and should be scrapped.
We simply must use profiling to the fullest extent possible as the first layer, and then use other methods for those who “fail” the profiling test.
