And in their fervent zealousness to ensure they don't look like they're using race and to show that using race would be harmful (even though they almost certainly have not done an objective study to determine if race would be a useful qualifier), they will almost certainly pull aside otherwise non-suspicious white people for questioning and decline to pull aside "suspicious" looking "middle-eastern" types.

Sounds to me mainly like this is another excuse for them to deny legitimate claims of mistreatment by innocent passengers as there's no way more than one in a thousand pax will actually be doing something suspicious enough to warrant such investigation. (And in those cases, I'd rather the TSA leave it to the pros and let the LEOs do their job.)
