Near my old workplace there was an incident where somebody tried to set a fire at night and the police got involved. The criminal got away that night, but I was impressed that they actually caught him a few days later. I got to thinking about how you could do this with today's technology when you're recording things all the time... "Give me the license plates of all the cars that arrived after 11 and left the area between 12:30am and 1:00am?" To say nothing of tracking people using cell phones. (Recall that last bit was discussed in the Snowden leaks...)
