This one jumped out at me because of the hysteria about modifying the PCA to allow just that. The reason given for the unloaded guns was that the white House lawyers said loaded weopens may violate the Posse Comitatus act. As to the blue haired granny, how much of that is urban legend?
I'm sure that to some degree, it is a rhetorical example created to make a fact and as such, there is probably much exaggeration. I do recall the old French dude that got arrested for dropping his drawers at seeming overabuse on the part of the screeners and I have seen a few actual scattered news reports about an old lady with a metal knee being strip searched. Otherwise, I don't know.
My 14 year-old daughter had her shoes checked and got wanded going in and out of Puerto Rico last December, but young dark-skinned, dark-haired men didn't get the same treatment.
It's really the stupid PC insistence to not profile. There have been several reports of old ladies and men being 'random' searched, AL Gore was searched, etc.
It's more than urban legend, and as An Coulter said
One hundred percent of the successful terrorist attacks on commercial airlines for 20 years have been committed by Arabs. When there is a 100 percent chance, it ceases to be a profile. It's called a 'description of the suspect.'
