Do they *voiceprint*, too? Just a number and a few questions doesn’t seem to be quite enough as “documentary evidence”, IMO.
The call is archived in case of, for example (which has happened I think in Florida) someone broke into a house in a separate neighborhood and called police about a robbery going down in a neighborhood three blocks from the callers house. Cops showed and were ambushed, killing one. One ambusher got killed which led them to the driver and second shooter. During the investigation another person called to ask about bail or something and the call was compared to the 911 call. The cops said the second shooter was ready to be released on his own recognizance. When the dude showed up he was arrested. Other than the dead guy,the shooter, driver and caller were adjudicated guilty of first degree murder. NBP’ers. Holder’s peeps.
