Motive can be fully inculpatory or exculpatory or only partially inculpatory or exculpatory. According to a police representative, the undercover operation yielded neither inculpatory nor exculpatory evidence. Exculpatory evidence is evidence that might exonerate the defendant. Exculpatory evidence may include biased witnesses, mistakes, or entrapment. Whether the government must disclose exculpatory material during plea bargaining is an open question. Ballew's attorney pointed out exculpatory evidence ignored by the ATFD. The coroner did not disclose the second exculpatory report to the defense. Bosch talks to Elias' private investigator, who reveals the exculpatory evidence that Elias uncovered. His exculpatory findings were criticized by Amnesty International.
