Flipside Up
At a certain uk airport we do not ask "do you have any dangerous items in your hand luggage," we verify that for ourselves.
I was basing my comment on what happens when I check in at LHR and LGW, since I believe that the airline personnel are required to ask these questions by law. So I assume from your reply that you are a security person.
Would you therefore be happy if we removed said items specified as being potentially dangerous?
Well, you might also need to remove a lot of other things too, including my belt, which can also be used as an improvised ligature and what about my hands? As a Karate black belt, you might be worried about those too?
Your comment just proves my point, it is intent that determines what is and isn't a risk. Apparently the authorities accepted that the Italian man had made a genuine mistake and was not a threat, although I totally respect the cabin crew for their swift professional actions.
As for profiling, please enlighten me, what does a potential terrorist / potential suicide look like
I have no idea what a potential terrorist looks like and I believe that there is rather more to profiling when done properly, maybe you should ask someone at El Al, who seem to be rather good at it.
and do we exclude all air crewe as being altogether on a higher plain
Well, firstly I think that you mean "plane", not plain.
Grammar is obviously not your strength?
I don't see why air crew should be excluded from checks nor security personnel. By the way, I am not air crew, just one of the punters who pays the security peeps wages by means of pax tax.
