Actually there is nothing really ethically wrong with the technology there is depending on use and like you say it could be used to frame people.

What is more likely is that Video and Audio evidence are less likely to be considered as a means of evidence on how easy it is to manipulate.

that is more likely than halting advances technology.

This could certainly spell an end to the CCTV cameras everywhere if they can not be submitted as evidence or it makes it lesser evidence. It’s actually pretty sketchy anyway even now and I don’t think anyone can be charged by CCTV alone unless it’s like a traffic or parking or speeding.(Racketeering / fund raising in some cases especially parking and congestion zones)

I think you still need a witness / victim and some sort of complaint to compliment any footage with most crimes at least I think that sounds about right?
