The Freedom Summer Murders

 

    Some aspects of the official narrative on the Freedom Summer murders leaves me with doubts and questions about the official narrative.

-An anonymous informer gave the FBI a general location of the bodies. Instead of having the work crew dig from one end of the earthen dam to the other, a federal agent marked a spot where he wanted them to start digging and just happened to pick the exact location of the bodies. 

-Documentaries say the informer that told the FBI the location of the bodies is known only as Mr X because he still lives in the area, apparently assuming that the KKK would not know the identity of the only klansman that knew the location of the bodies. 

-How or did the FBI confirm the Klan membership of those that provided evidence, signed statements, or testified against the Ku Klux Klan?

-Why was it unnecessary for Klan members that provided evidence, signed statements, or testified against the KKK to change identity or location?

-What was the hard evidence against the men convicted in this case? (Not saying there wasn't any, just curious about what it was.)
