Let's face it, 90% of people are fucking stupid, and believe everything they see on TV, including "crime dramas" where unbelievable feats of forensic science are achieved in every episode. People eat this shit up, and most of this stupid underclass believes it is necessary to prevent or solve crimes.
This is why the revelations that these ubiquitous, omniscient surveillance systems exists generated nothing more than enthusiastic yawns among the populace.
People... just... don't... care...
Honestly, the people who do care, even being as vocal as they can be, make an almost imperceptible noise against the drums of big tyrannical government - like an annoying mosquito in the ear of the underinformed, low-information majority who just wants to know when the next episode of the Kardashians or Property Brothers or CSI or other mindless drivel will be on.
