Tripower455,
Your argument is only valid if a pilot only had access to his/her individual aircraft. Once beyond security gates, that is not the case.
Sure it seems assinine to hassle a pilot over scissors, etc., when he will shortly be sitting next to a fire axe, and in command and control of a passenger-laden craft. But surely you can see how any employee group, if routinely not screened, has the potential to smuggle firearms/explosives for distribution to comrades in the secure area, for taking control of multiple aircraft.
I don't see terrorists and any employee group being mutually exclusive. If ramp employees are for some reason considered such, I fail to see the logic. Especially considering that a would-be terrorist would find it much easier attaining such a job.
Airport security is indeed a bit of a joke, both for ridiculous policies in some cases, as well as having to deal with the rent-a-cop screeners. Same mentality as the as the mall security guard, or nightclub security 'bouncer', etc. ... they love being the big fish in their little pond at times.
Still...noone should be 'trusted' to the point of coming and going as they please.
