There are US cities with drones in the air taking pictures of the city. Say somebody robs a bank. Review the picture history from when they arrived at the bank, go backward watching their car until you find out where they live. Drive over and arrest them.

This 'time machine' feature of ubiquitous surveillance is going to be a brave new world.

Better dash camera on police cars, and police body cams, mean they always have your plate number. You cannot run for fun if they already know where you live/work.
