Dave put two and two together.
Let’s say police around the country get photos and profiles of everyone who drives their cars too fast, forgets to stop at stoplights, turns without signaling, and, well, you get the idea. All those photos and profiles can go into a database and AI and machine learning slice and dice the data in such a way that you could be charged with a crime that have not yet committed; but you will.
You could be charged with Pre-Crime because Big Data is the Precog of crimes you will commit. Look how much time is saved.
