A year after a foiled plot to bomb a US-bound passenger plane, Homeland Security Secretary Janet Napolitano told CNN's "State of the Union" program that other places and modes of transportation must now be scrutinized.
"We look at so-called soft targets -- the hotels, shopping malls, for example -- all of which we have reached out to in the past year and have done a fair amount of training for their own employees," Napolitano said..
"The overall message is everything is objectively better than it was a year ago, particularly in the aviation environment. But we're also looking at addressing other areas," Napolitano said..
"And so we have enhanced measures going on at surface transportation, not because we have a specific or credible threat there, but because we know, looking at Madrid and London, that's been another source of targets for terrorists."
