I should add ... the selection for NoS is done by "randomizer" (fancy word) ... step on the mat, get the lucky arrow, or not. Left Arrow - you've been selected, right arrow - old fashioned security. (automatic NoS if you've been SSSS'd). But at least it's not a person trying to be random (by selecting Women and teenagers) - CATSA has tried to take that out of the equation.
