If this is all the info the prosecution is relying on, then its a easy walk for GZ. Without hard forensic evidence that contradicts statements and the account of GZ, he will walk no matter what.
It is not all they have. In this affidavit, they will put in the least they have to just to establish just cause...so the judge will rule there is enough evidence to hold him over for trial. That is all they give you in this initial reasonable cause affidavit.
Is this maybe intentional on prosecution part? Have a bad ass trial and then not enough of substance to give to jury and GZ walks.
Persecution would not have blood on their hands and GZ & his family move to someplace like New Zealand.
