CEP Executive Director David Ibsen writes: "Before launching his shooting rampage at a Walmart in El Paso, Texas, 21-year-old Patrick Crusius posted an anti-immigrant screed on the online messaging board 8chan. 8chan has become a popular vehicle for extremists to share hateful content and glorify mass shootings. After the massacre in El Paso U.S. policymakers and tech companies are finally taking notice. Last Friday, the White House hosted a meeting with tech companies to discuss violent online extremism. President Trump also called upon the Justice Department to work with local, state, and federal agencies as well as tech companies to develop tools that can help detect potential mass shooters. Additional hearings are planned by the House Homeland Security Committee, which has asked 8chan founder Jim Watkins to testify about the proliferation of extremist content."
