Hugh Pickens writes "The Hill reports that Homeland Security Secretary Janet Napolitano says terrorists will continue to look for US vulnerabilities, making tighter security standards necessary. '[Terrorists] are going to continue to probe the system and try to find a way through,' Napolitano said in an interview with Charlie Rose. 'I think the tighter we get on aviation, we have to also be thinking now about going on to mass transit or to trains or maritime.' Napolitano added she hoped the US could get to a place in the future where Americans would not have to be as guarded against terrorist attacks as they are and that she was actively promoting research into the psychology of how a terrorist becomes radicalized. 'The long-term [question] is, how do we get out of this having to have an ever-increasing security apparatus because of terrorists and a terrorist attack?' says Napolitano. 'I think having a better understanding of what causes someone to become a terrorist will be helpful.'"
