How could step one be anything besides the store taking a 2€ minus on their spreadsheet, instead of stopping flights. So many ways to hide a ceramic knife instead of a stupid pair of scissors uselessly incapable of doing anything on a plane.
All of these “security theatre” measures are just pure incompetence institutionalized due to 911, that managed to do nothing, just some security equipment manufacturers rich, and plane clients quite annoyed.
Hell, derailing a train would cause more human life / infrastructure damage, than a potential “guy has sharp object and cant do shit to the plane piloting” shit boomers are somehow still, in their old age, surprisingly afraid of.
Cars, trains, trucks all move freely, but somehow planes are terrified of extremely remote chance of bad actors trying to make a 911-esque political statement? (Because it’s about the fanfare not actual damage, mooost buildings are much less secure than people would think)
