I was thinking about how cool it’d be to hook up witnesses to a crime to get a good look at the perp... Or hook up a [still living] terrorist to get a look at all his contacts and all the places he had been for the last few months before he committed the crime. You might even be able to use it as a lie detector... If the image he’s describing is nonexistent or not clear enough, you might be able to tell he was lying, etc. The possibilities are staggering.
The possibilities for abuse are staggering too.
