Weakness of US Passports and Smart Cards (Jerusalem Post)

sorry, but the problems with the rfid passports were demonstrated
years ago, long before they were officially mandated. the response
from the Dept. of Homely Scrutiny was essentially
"bad guys aren't smart enough to exploit this".
there are a bunch of people with really important jobs
in our gubmint that are just too stupid to be believed.
it's a miracle they haven't cut themselves on an apple
and bled to death long before now.
it's one thing for a leader to not know the details
but surround himself with people who do and can give
him good advice. it's another things entirely when
those people are either ignored or they aren't
there in the first place.
and then after the obvious comes to pass,
everyone is surprised. stupid stupid stupid
not nearly enough chlorine in the gene pool
