The could be true, but Giuliani never offered it in court as a justification of his accusation against Freeman and her daughter.
I think that's why the recent hearing is so confusing. Guiliani admitted the facts before the court are not contested, from his case perspective. That is not admitting guilt. The cheaters didn't know about the convention site security cameras (for slip-n-fall surveillance) until after the case had been presented. And the Joe Hoft expose of the National Preemptive Emergency Cellular Network isn't a month old yet.
