"[Oswald's death] will allow, I am afraid, a lot of civil rights people to raise a lot of hell because he was handcuffed and had no weapon," Hoover said. "There are bound to be some elements of our society who will holler their heads off that his civil rights were violated --
which they were."
Hoover said that the FBI had warned the Dallas police of threats to Oswald's life and that the city's police chief, Jesse Curry, had assured the bureau that Oswald would be properly protected.
"However," Hoover's memo reads, "this was not done."
-There is a document from Hoover that references the fact that Oswald's rights may have been violated based on the failure to protect him while in police custody. I'll try to find this memo.
