ISIS’s online radicalization efforts present an unprecedented danger.

Consider a law that makes it a crime to access websites that glorify, express support for, or provide encouragement for ISIS or support recruitment by ISIS; to distribute links to those websites or videos, images, or text taken from those websites; or to encourage people to access such websites by supplying them with links or instructions. Such a law would be directed at people like Amin: naïve people, rather than sophisticated terrorists, who are initially driven by curiosity to research ISIS on the Web.
