For several years I have noted here and elsewhere how poor the security is at all airports I have gone through. True, the attempted theft of my laptop by security officers happened prior to 2001, so I haven't had that particular problem again. But, on business and otherwise, I travel enough to be discouraged by all airline and airport security measures. US and International.
Totally porous.
That being said, as a resident of MLN and CT, I have to blame Joe Lieberman.
