That I could see as a plus - maybe even base their entire ad campaign around it. Using these as creep show, or worse, should not be allowed. In order to "film"in public an apparent camera of some sort should be used so as to notify those being filmed.

That’s fair, isn’t it?

Do they work when driving? Maybe a sunglass version? That would be handier than window mounted cameras and the like. Fuck 'em if all they’re for is privacy invasion. Enough of that shit is enough.
