Its a good movie. Unfortunately, the reality isn't so cinematic. J Edgar Hoover sent just 11 agents to the town, and not the hundreds depicted in the film, and most of them allegedly only intervened when absolutely necessary, and in some cases they supposedly stood by while beatings took place right in front of them.

Also sad to report that no klansman testicles were actually harmed on the road to justice. Instead, the FBI just did some good old fashioned bribery. The Bureau paid Klan informant James Jordan for information on what happened to the activists, and he obliged.
