Also, he said, the FBI has a policy against revealing the identity of confidential informants like Burns unless they agree to go public. And agents may have been leery about sharing the information with state and local police forces, which were known to have Klan sympathizers.
As for the tapes secretly made in Blanton's kitchen in 1964, computers were used to enhance the murky recordings and help decipher the voices for the jury at his trial – technology unavailable in the 1960s and extremely time-consuming in the 1970s when Baxley was pursuing the church bombers.
The tapes were only "moderately intelligible" without enhancement, said Anthony Pellicano of Forensic Audio Laboratory, the Los Angeles company that performed the work.
But the FBI did not let Baxley know the tapes even existed in the 1970s. It wasn't until the latest investigation began that Baxley found out about the tapes and the informant. Yung said he learned of the long-secret evidence as the Blanton trial unfolded.
"They denied having any more evidence than what they gave us, and it was hard enough getting what we got," Yung said.
With Hoover running the FBI, the case was closed in 1968 without any charges. The file of FBI evidence against Chambliss, Blanton and others sat dormant.
Hoover died in 1972, but his successors also left the tapes and other evidence in storage. Finally, Rob Langford, the agent in charge of the Birmingham FBI office, decided to reopen the church bombing probe after meeting with black ministers in 1993.
FBI agents spent months going through the old evidence and found the tapes and written reports compiled by Burns. The tapes went from storage to experts who enhanced their quality and then to prosecutors. U.S. Attorney Doug Jones was deputized to handle the state case, and Burns was brought in to testify before the grand jury that indicted Blanton last year.
"No matter what J. Edgar Hoover said and no matter what his reasons, the FBI and the agents that were on the ground … did an absolutely incredible job," Jones said after the verdict.
Baxley, in his op-ed piece in the Times, said "rank-and-file FBI agents working with us were conscientious and championed our cause." Without naming anyone, he said his disgust was with "those in higher places who did nothing."
