***Unless you think mobs aren’t evil, more or less by definition.****
From what I’ve read, many, not all, in that mob were former Mormons who realized what Smith really was, a fake.
I have heard that as well. Also, there is some evidence that Smith thought at least part of the mob outside was there to break him out of jail and that he recognized a few of them because he used the Masonic signal of distress before falling out the window.
If Smith really thought that the Governor would protect him, why did he have 2 guns (and some liquor) smuggled in?
