You enter a jewelry store with a drawn pistol when there's no robbery in progress , then you are the felon.
The indictment has clearly anticipated the, "I truly believed the election was stolen and acted in good faith" argument. (By noting that Trump ignored the army of attorneys in the Justice Department, his own hand picked Attorney General, his own head of Homeland Security, his own Vice President, etc., etc., and deliberately surrounded himself with lunatics.)
Lauro (at least) seems to be focusing on Trump's right to believe what he wanted to believe without getting into the "why" of it.
