If you publish it, it&#x27;s libel.  There&#x27;s a difference between &quot;so-and-so is an asshole&quot; (not a fact, haha), and &quot;so-and-so committed a crime&quot; (a fact).  Whether it&#x27;s a civil or criminal matter depends on the jurisdiction.  The UN is against criminalizing defamation because it limits freedom of expression.
