EveryCRSReport.com – Terrorism, Violent Extremism, and the Internet: Free Speech Considerations, May 6, 2019 R45713: “Recent acts of terrorism and hate crimes have prompted a renewed focus on the possible links between internet content and offline violence. While some have focused on the role that social media companies play in moderating user-generated content, others have called for Congress to pass laws regulating online content promoting terrorism or violence. Proposals related to government action of this nature raise significant free speech questions, including (1) the reach of the First Amendment’s protections when it comes to foreign nationals posting online content from abroad; (2) the scope of so-called “unprotected” categories of speech developed long before the advent of the internet; and (3) the judicial standards that limit how the government can craft or enforce laws to preserve national security and prevent violence.

At the outset, it is not clear that a foreign national (i.e., a non-U.S. citizen or resident) could invoke the protections of the First Amendment in a specific U.S. prosecution or litigation involving online speech that the foreign national posted from abroad. The Supreme Court has never directly opined on this question. However, its decisions regarding the extraterritorial application of other constitutional protections to foreign nationals and lower court decisions involving speech made by foreign nationals while outside of the United States suggest that the First Amendment may not apply in that scenario. In contrast, free speech considerations are likely to be highly relevant in evaluating the legality of (1) proposals for the U.S. government to regulate what internet users in the United States can post, or (2) the enforcement of existing U.S. laws where the government seeks to hold U.S. persons liable for their online speech.

Although the government typically can regulate conduct without running afoul of the First Amendment, regulations that restrict or burden expression often do implicate free speech protections. In such circumstances, courts generally distinguish between laws that regulate speech on the basis of its content (i.e., the topic discussed or the message expressed) and those that do not, subjecting the former to more stringent review. A law that expressly restricts online communications or media promoting violence or terrorism is likely to be deemed a content-based restriction on speech; whereas a law that primarily regulates conduct could be subject to a less stringent standard of review, unless its application to speech turns on the message expressed. Whether such laws would survive First Amendment scrutiny depends on a number of factors…”
