You seem woefully unaware of the inconvenient fact that in the one trial he had, where he was represented by counsel and allowed to present a defense, he was found guilty beyond a reasonable doubt in a court of law.

It must be nice living in your world where OJ didn't kill Nicole, Ray Rice is a perfect angel, and everyone is conspiring against poor, sweet Hardy.no it doesn't
it is non-binding, he had to arraigned again since his 'real' trial had not yet begun and this time his Constitutional rights had to be respected
