Today many people scratch cars just for the sake of it, robber things, use things that dosent suppose to use and you probably never find the responsible. If you need to know who was, you have to bring everything to a lab and it cost lots of money and then you have to find similar digital prints in a criminal records data.
What about if in the future our DNA and finger prints are registred? what about if we have a tool that can identify dna and finger prints in few minutes? this will absolutely reduce crime in society. you possibly could live your door house unlocked.
Do you think this will be possible in few decades ?
Today my sister stole me one more time my tooth paste ....I wish I had a tool like that even for very small things like this lol
