The FBI opened an investigation immediately after the 1963 bombing and assigned it the case name BAPBOMB. Agents gathered physical evidence, interviewed witnesses, and focused on Ku Klux Klan members.

Yet no federal prosecution followed during the original investigation. Evidence problems, witness fear, legal limits, and decisions by powerful officials helped justice recede.

The first conviction

Alabama reopened the case in the 1970s. Robert Chambliss was convicted of murder in 1977, fourteen years after the bombing.

The conviction showed that an old case was not necessarily an impossible one, but two more decades passed before renewed investigations produced further trials.

Cases reopened

Thomas Blanton was convicted in 2001 and Bobby Frank Cherry in 2002. The passage of time had cost witnesses and evidence, yet changed circumstances allowed testimony and records to be used.

The investigation’s history is both a record of persistence and an indictment of delay. It asks why institutions that could identify racial terror were so slow to impose consequences.
