The 2016 election left many in America afraid – of intolerance and the violence it can inspire. The need for trustworthy facts on the details and frequency of hate crimes and other incidents born of prejudice has never been more urgent. There is simply no reliable data on hate crimes. And no government agency documents lower-level incidents of harassment and intimidation, such as online or real-life bullying. Understanding and documenting incidents like these - from hate inspired murders to anti-Semitic graffiti to racist online trolling - requires new approaches. In the wake of the deadly anti-Semitic attack at the Tree of Life synagogue in Pittsburgh, ProPublica and FRONTLINE present a new investigation into white supremacist groups in America - in particular, the neo-Nazi group Atomwaffen Division, that has actively recruited inside the U.S. military. Continuing the reporting on violent white supremacists in the U.S. which has helped lead to multiple arrests, this joint investigation documents the group’s acts of violence and asks how aggressively civilian and military authorities are taking the group’s terrorist objectives and how it gained strength after the 2017 Charlottesville rally.
