Jack the Ripper breakthrough as DNA 'finally unmasks serial killer'

Yeah but those don't usually go unsolved for 150 years and it seems very unlikely that any of the British historians involved in this project would be able to make enough meaningful changes to the American sociopolitical landscape to offer any help on that subject.

Jack the Ripper was the first well-known case of a serial killer. There were previous serial killers, but their killings did not have the international publicity that Jack the Ripper had. It was perfect newspaper fodder given the seedy location of urban London and the lurid details of the murders of prostitutes coupled with things like telegraph cables covering the world and crossing the oceans. And, as others have said, it was never solved.

So obviously people have wanted a resolution to something like that for decades.

There are things worse than that, even. And those things invalidate discussion of american school shootings as much as the shootings should invalidate this discussion.
