Joe Smith was charged with ordering the destruction of the Nauvoo Press. Smith was a false prophet hack and everyone around him knew that. He was shot escaping from Jail. Simple as that. It wasn't "murder" in the slightest.
Joe Smith knew NOTHING about religion. Just a charlatan putz who should've continued selling beer from his home. (at least he had a legal license to sell booze from his house).
I just looked in the Dictionary under LOU-ZERRR and saw Joey Smiths goofy mug. (also listed under "big fake").
Thankfully lots of mormons are waking-up and bailing from the cult.
