Have you ever watched the documentary The Thin Blue Line by Errol Morris? Incredible.
It brings home the point that the innocent often appear guilty while the guilty appear innocent. The guilty have everything to hide so they become expert at doing things to win everyone’s trust. Cosby would never tell a suggestive joke because he’s so wholesome, America’s father.
The innocent have nothing to hide, so they they don’t take their trials seriously and are rightfully angry about being put on trial, not a demeanor that endears them to juries.
