Yes, the State put up a lot of people, that didn't prove any crime was committed. The jury is frankly pointless, either they get it right, or the NY Court of Appeals will fix it.Correct, the defense need not present any defense at all.
They are free to simply claim the prosecution didn't prove their case.
The reality is the prosecution entered mounds of evidence and called over 20 witnesses to prove their case.
This week it will be before the jury to render their verdict.
