While I'm thinking about it, we should be looking at ways terrorists could attack buildings from the outside as well as inside. I can think of some ingeneous scenarios that could at least cause serious damage . . . and a possible foil for something to come later.
Sure hope window washers are carefully screened. They could also be used to perform outside security checks.
I'm thinking if they tried to pull a Cole-type attack on a building instead. Gotta prepare for these ugly possibilities.
Maybe, just maybe, they were right. You people never cease to un-amaze me. America.
