Replacement of outdated "security" with outdated "security"? No thanks.
Unfortunately, the voodoo "security" approach (read: akin to TSA BDOs) is what IATA, the UK government, BA and FR (amongst others) are looking at as the "replacement". That may "channel" the harassment in the guise of "security" but it will not eradicate the stupid "security" measures.
Villains who twirl their mustaches are easy to spot; those who clothe themselves in good deeds are well camouflaged ........ waiting for the right climate in which to flourish, spreading fear in the name of righteousness.
The one aspect of the current track of dialogues taking place in this regard which might actually eliminate some of the stupid "security": creation of a "safe" zone eliminating/ratcheting back the "security" measures applicable to transit passengers originating from the "safe" zone flight(s). Even that won't happen any time soon since that would require further changes to the physical plant of airports. And I doubt it would involve the US engaging in full reciprocity in this regard.
