I suspect the same. The historian and beloved admirer of King has spent years researching and writing very positively on King.
Now he has unearthed a treasure trove of documents that reveal the complete nature and confirm decades of rumor and innuendo.
Garrow has ignored or quelched Kings communist support and blatant serial plagiarism to paint King in the most positive light and maintain King’s sainthood status.
I guess he had a really gross reality check and decided to be honest and not let the secrets lie till 2027.
Now that he has gained access, others could FOIA the same records.
