Yes, there would. I guess that would be, broadly speaking, understanding the threats—again I'm speaking specifically of terrorism—and understanding that the binary distinction between homegrown terrorism and terrorism that originates abroad is flawed. Many of the cases I've looked at in the U.S. with homegrown terrorists have included individuals who have travelled to Pakistan, Somalia, and some other dangerous parts of the world, so it's also understanding that your immigration procedures and your border control procedures need to be linked with the efforts of local law enforcement and law enforcement up to the national level in order to truly be fully effective in fulfilling national security objectives.
