Consider this:
“Witnesses are not subject to any cross-examination. The rules of evidence do not apply, so evidence that could not be admitted at trial (e.g. illegally obtained evidence, hearsay) can still be presented to the grand jury for consideration”
If the grand jury thinks there might have been perjury it sure as hell happened. The grand jury is in the total control of the prosecutor. If the jury thinks perjury happened the prosecutor KNOWS perjury happened, probably with his connivance.
A defendant has the right to cross and confront a charge or witness in a trial. He does not have this luxury before a grand jury. I have always felt this is an injustice of our legal system. A corrupt prosecutor with the monetary backing of the state can bring charges and trial and bankrupt an innocent man by political design. It is called “Lawfare.”
A prosecutor who knowingly brings a frivolous charge must be held to account.
