Uncorroborated accomplice testimony is insufficient to convict someone.  See <a href="https:&#x2F;&#x2F;www.justia.com&#x2F;criminal&#x2F;docs&#x2F;calcrim&#x2F;500&#x2F;708.html" rel="nofollow">https:&#x2F;&#x2F;www.justia.com&#x2F;criminal&#x2F;docs&#x2F;calcrim&#x2F;500&#x2F;708.html</a>, among others.<p>Why was he convicted?  Because the law matters only when it&#x27;s convenient.<p>I used to believe that &quot;ignorance of the law is no excuse&quot;.  I no longer do.  The people enforcing the laws (prosecutor, judge, police, etc.) are explicitly protected from misapplying the law.  There <i>are</i> excuses for them for not knowing the law, or not applying it correctly.<p>I claim the same rights as them.  If ignorance of the law is an excuse for them, it&#x27;s an excuse for me.<p>And yes, on the bare face of it, your friend should have been found not guilty.
