What is your suggestion, then? Only check the people wearing turbans? Don't you suppose that after a while they'll catch on and start sending people that no-one would suspect?
Don't be stupid - start with that as a premise and move forward cautiously. And if you find Morgan agreeing with you, review your position quickly.
You miss the point entirely. Any system that follows a specific pattern can be easily attacked. A degree of randomness gives those attacking the system more pause than a known pattern that can actually be used to their benefit.
Not at all. I am all for the randomness - right up to the point of ridiculous. In this case the child was checked via scan, parents offered a second scan - and then TSA felt the pat down was required. I would offer anyone can see the point of stupidity.
Insofar as profiling - it is an assist to identification - and it does require that one not rely solely on the "characteristics" offered. Otherwise as you note - the bad guys simply adapt. Now - in the instant case - was she 6? Was she traveling with family members? Did the scan really inadequate to the point of requiring a pat down... I sure don't think so - you?
