If ALPA was serious about solving the hijacking problem, then they would deter impediments to the solution:

Case in point:

The Northwest pilots hat carried small knives and a corkscrew through security on 13 Sep (PHX). ALPA should have suspended these members. It is not the place of those pilots to test the security system, much as it is not my place (although I wish it was) to question the qualifications and abilities of their pilots.

From firsthand experience, the pilot in the PHX incident said that he didn't feel comfortable flying with such loose security.
