brigham young: joseph smith never broke any laws...oh wait, yes he did

brigham young states in his journal of discourses:

Vol. 10, p.111
Joseph Smith, in forty-seven prosecutions was never proven guilty of
one violation of the laws of his country.

first off, if joseph smith was so innocent, why would brigham young use the deceptive words "was never proven guilty" instead of simply stating:
never violated any law of his country
?
oh wait....except for the time when he admitted to deception and was convicted of a misdemeanor?
