Imagine the parallel. Everybody's familiar with physical forensics. That's something that's well accepted. We've all seen CSI. I think most people understand it. You can leave a trail behind at a crime scene that can be collected by the police and held in perpetuity.
We've made a number of arrests decades after a crime has occurred because we've been able to collect that information and hold it. Digital evidence is very similar to that. It's a footprint. It is as important to contemporary policing and public safety as forensics is to us.
