The invasive airport scanners have caused quite a stir recently. Security is something to think about as many of you hit the road for Thanksgiving. In the future, we might find the scanners in places like the metro.
Homeland Security Secretary Janet Napolitano said on Charlie Rose:
Well, I think [terrorists are] going to continue to probe the system and try to find a way through. I think the tighter we get on aviation, we have to also be thinking now about going on to mass transit or to train or maritime.
Napolitano said we actually don't know much about terrorists, adding that:
If you ever try to divide template about what connects this terrorist to this terrorist and how they were raised and what schools they went to and their socio-economic status or this or that, it’s all over the map.
