I have a smaller chance of being murdered than being robbed. Mere frequency doesn't make one crime lesser or greater than the other. It's possible to be cognizant of two wrongs and commensurately apply the appropriate remedies to each one. There's no reason to operate on the fallacy of there being only one problem to think of at any given time or to presume that covariance doesn't exist.

You are certainly right in the short term, but this no-fly list process, like any extraordinary process put in place in extraordinary circumstances, esp. around air flights, will stick forever.
