Here's the abridged version: mainly, his struggles with polygamy consisted of
#1 hiding it from his first/legal wife, Emma, as long as possible. (When she found out, she was livid).
#2 hiding it from the general membership as long as possible. (In the beginning, for many years, it was a dirty little secret only shared with and practiced by a very small circle of his friends. Which tends to lessen the validity of the eternal salvation angle - because why should that be available only to a select few?. The women they chose to marry were complicit in keeping it secret).
#3 hiding it from the husbands, brothers and fathers of the wives he and his minions were acquiring. (Many who objected were invited on excursions by his outriders, from which they never returned).
#4 hiding it from authorities and neighbors. (While breaking into homes, stealing crops and rustling livestock because those who practiced the principle had too many mouths for one man to feed).
#5 hiding from the membership that the tithing books were being cooked. (See #4).
It truly is a shame that an angry mob stormed the jail where he and his brother Hyrum and some others were in custody. They were murdered; after so many years citizens were fed up with him/them skating time after time.
All told, including the times when he fled state jurisdictions and/or federal judges set aside state arrest warrants, history would have been better served if he had lived to face trials on charges of illegal banking, bank fraud, perjury, inciting to riot, treason and conspiracy to commit murder.
None of that will be found in books written and approved by members/church historians. You will need other sources to get the big picture.
