How do the actions of the court reveal disregard for the truth?

The judges accept spectral evidence (testimony of citizens who claim to have witnessed supernatural events) without corroboration. During the trials, Abigail and the other girls who participated in the conjuring all pretend to be victims of witchcraft rather than instigators of wrongdoing–all, that is, except Mary Warren. John Proctor prods her to tell the truth about the girls and, specifically, about the poppet she made for Proctor’s wife. She agrees to do so, although she is terribly anxious about contradicting the other girls. This sort of evidence can be found throughout the novel. Just take a quick look, you will find it!
