Reinforced cockpit doors and the new assumption that hijacking = death already prevent another 9/11 from ever happening. Justifying every little bit of paranoi

Reinforced cockpit doors and the new assumption that hijacking = death already prevent another 9/11 from ever happening. Justifying every little bit of paranoia because you're very very scared of some unknown threat is deeply irrational. Proportional responses are fine - unusual behavior merits further observation or inquiry, not pushing a big red button.
