Law enforcement does counter political extremism here in the United States in the exact same way that they do political extremists who are infiltrated into the United States, who may come from a religious motivation, as we saw overseas in Europe. But the same methodologies have to be used.

We have this unfortunate habit in the United States of dividing terrorism into different categories. External, foreign terrorism, which manifests itself overseas or in the United States, or domestic terrorism.

ISIS rules Muslim apostates every day and then beheads them. Poorly educated guys get Islam for Dummies, petty criminals who think they're suddenly changing their lives because they see the light. The best way to fight them is to show them they don't know Islam at all, and that they are in fact working for the other side.

Most ISIS members are irreconcilable. Once they've bitten that bug, that cultish bug, they would prefer to die. They're going to be given the opportunity, no one's going to get out alive from Iraq and Syria now. They make sure everyone's a suicide bomber now.

There`s actually some fluidity here in the United States. Using local intelligence against [terrorism].But you still have to infiltrate these groups. You still have to collect intelligence as you see fit. And they are organized. They are very well organized in the anti-abortion movement. Ideologically, they`re almost the same. And that`s where we see these spurts of violence.

There is no difference between an ISIS gunman and an American gunman that goes into a mosque, or the gunman Baruch Goldstein who went into the mosque in Bethlehem and killed 29 guys about fifteen years ago. Goldstein took his service weapon and tried to kill everybody in the mosque. He shot over a hundred people. There's no monopoly on terrorism. Terrorism experts know this and we live according to that.
