Oh brain fade,
The reason all crew go through security is because "they" are terrified that terrorists are going to grab some uniforms and mascarade as pilots. That's because there is no universal identification system, and currently no way to check the 'pilot' presenting is, in fact, bona fide. So rather than implement such a system the easiest way is just screen all pilots. Many of us have been arguing for years that there should be such a universal system to confirm this to be a legitimate pilot and the authorised pilot of flight XYZ.
And if a Capt's wife and kids really are being held hostage whilst Capt tries taking something through, WHY do you think he's more likely to "express his concerns" to security goons vs making a mobile phone call to the cops? If he hasn't made such a phone call then he's hardly likely to 'fess up to security - he'll probably just stay silent and hope to get through!
But mate, this is a tired, tired old conspiracy theory - usually dreamed up by clones in dark rooms who, frankly, seem to be 50% ex-military types who've lived in a different world! It is so improbable! This is not how these guys work - there is too big a risk of being foiled. Far more likely scenarios are exactly what those fellows in England are going to jail for, and the 7/7 chaps. CAN YOU NOT SEE THIS?
We are wasting untold manhours confiscating Captains' nail clippers, shaving cream and bottles or water when the resources should be focused elsewhere. In Australia airside workers (engineers, caterers, cleaners, etc) are still, yes STILL, going airside with just a cursory look at by security. They don't confiscate their water or any other liquids or even their weapons - because they are not metal screened! They go in the side gates still and it's "too expensive" to set up proper screening points at each gate.... Well, these people are arguably just as susceptible to your hostage conspiracy. So why isn't being addressed there?
So brain fade, where do you see the biggest threat? A freighter Captain wanting to take a bottle of water on a 12 hr flight? An airside worker going to play with an aircraft unscreened? Or perhaps some disgruntled radical youths building a fertiliser bomb and driving a van - unscreened - into a shopping centre carpark?
Where's the biggest threat, mate?!
My argument as presented here is disjointed and circular, because frankly, I'm too frustrated with insane attitudes like yours to spend anymore time re-writing it! Virtually all professional pilots agree with me and have had a gutful of insulting, ineffectual "security" measures being imposed on us. Not one single pilot has been caught. Meanwhile our side gates, our shopping centres, our train stations, our beaches, our main streets continue to be wide open because of narrow minded thinking, such as yours.
You're welcome to the last word, mate, because frankly you are not the bloke I need be arguing with to change things!
