Retrojective Goggles (RAR!)

[Elheru Aran]

One presumes that, say, a government office would have such. Most stores have cameras at least; even if they can't see into the past, they can bloody well see a yahoo standing around with funny goggles on his face. For reasons of security I would fully expect there to be a clamp-down on just anybody using these in public unless they're obscenely common.
