I'm reminded of the way that universally carried high resolution cameras made UFOs and crop circles disappear, but police suddenly became a lot less trustworthy.

The abuse question .. well, "social justice" is a term that starts fights, but there have been a lot of people who've been able to get some sort of justice only because they raised their cause on social media, having been ignored by the authorities. #MeToo is probably the big example, culminating in the Epstein revelations.
