Reminds me a lot of a persistent surveillance program they've tested in other cities. The idea is if you record all movements in a city from the air, you can trace where criminals come from or where they go. This system has not been implemented in a major American city, to my knowledge, because of the privacy issues. Excellent Radiolab episode about it: http://www.radiolab.org/story/eye-sky/ http://www.radiolab.org/story/eye-sky/
