" cannot use this data to recreate anything remotely resembling the original dataset." This by itself may be mostly true perhaps - and many of the comments get into ways of playing with this dataset to make it better, I don't have experience with those methods, but, what I have not seen anyone mention, if you have this dumbed down dataset, the original is gone.. you can still combine with other data sets that are either public or previously created and likely fine tune; dumbed down set + public voter records + public arrest records + previous whatever records - sort, match, what's left over. and pretty much recreate what you needed from the original, maybe not 100%, but I would guess you could get really close.
