The grand jury isn't a trial jury. They don't need to see evidence of innocence because a GJ decides 'Is there enough evidence to support the charges?' That's ALWAYS been the purpose of a GJ and the intent when the original laws for GJ were written.Actually, they're pointing out a lot of things the prosecutor did leading up to the GJ hearing that were dishonest, the most important of which was providing the GJ with exculpatory evidence. It (the JG hearing) was a one-sided hearing. The Grand Jury only heard/read the cherry picked information that the prosecutor gave them. That's not how the US criminal justice system is supposed to work. Using today's hearing as example, it would be like holding the hearing only for the defense, not allowing the prosecutor to be present or submit any written argument or evidence.
ETA: I have to take off again, but will finish listening and respond later. Its interesting because its the first time we're hearing testimony about how the prosecution made their decisions in AB's case.
Some states allow or require exculpatory evidence, or a DA will provide it if it's a case they really don't want to try but are obligated to charge. But it's not required in NM apparently.
Innocent or guilty is decided at the trial by the real jury.
