Remember that scene from "Men in Black" where K watches surveillance video feed of his ex? In the movie it was meant to be wistful and cute, I guess. Now that such systems are getting closer to reality, you realize the potential for abuse in enormous.

More like his widow than his ex - he was unable to ever contact her, which is what made it cute rather than creepy.

I mean at least in that situation, K was forbidden from ever making contact with his ex, with far greater consequences.
