[JURIST] The US Department of Homeland Security (DHS) [official website] on Friday announced changes to airport security rules [press release], moving toward a screening system based on intelligence information. DHS Secretary Janet Napolitano [official profile] said the new system will apply to all air carriers with international flights to the US, and is more effecting at stopping terrorist threats:

These new measures utilize real-time, threat-based intelligence along with multiple, random layers of security, both seen and unseen, to more effectively mitigate evolving terrorist threats. The terrorist threat to global aviation is a shared challenge and ensuring aviation security is a shared responsibility. I commend our many partners around the world who have taken steps to increase their own security measures through deployment of new technology, enhanced information sharing and stronger standards to keep air travel safe.

The American Civil Liberties Union (ACLU) [advocacy website] praised the new policy [press release] as a move away from racial profiling, calling it a step in the right direction.
