I'm no tinfoil theorist, so I wonder. If a city is plastered with HD Cams (solar power, etc), would it make sense to go places at night then if you don't want to be seen? Or is infared really easy to add and would defeat those efforts?

More importantly, wait until these HD cams and other video cameras are hacked so that someone else besides the consultants, government, and myriad other actors has complete control. Straight out of a dystopia trope.
