Focused on 9/11, U.S. Is Seen to Lag on New Threats - New York Times: "The Department of Homeland Security has taken significant steps since the Sept. 11 terrorist attacks to make it much harder to turn a plane into a flying weapon. But a nearly obsessive focus on the previous attacks may have prevented the federal government from combating new threats effectively, terrorism experts and former agency officials say.

The arrests overseas this week of people accused of planning to use an explosive that would be undetectable at airports illustrates the significant security gaps, they said.

While the department has hardened cockpit doors and set up screening for guns and knives, it has done far too little to protect against plastic and liquid explosives, bombs in air cargo and shoulder-fired missiles, the experts say.

The nation is still at risk from the same “failure of imagination” cited by the 9/11 commission as having contributed to the success of the 2001 attack, several argued.
