The subtext is that the reason "those people" don't know their place, whether it's uppity knee-grows or smartass teenagers, is because now you have cameras everywhere to record when nutjob cops go off on them in, say, a classroom.
The reflexive counter to that is to point out that anyone supporting that dumbass cop in the South Carolina classroom is the problem. (More to the point, I know at least two people who have been to state prison, who vocally support that dumbass school cop. Talk about complete cognitive dissonance.) And indeed, they're part of the overall problem.
But it's really people like this who are the fucking problem -- a dopey second-grader being pimped by her star-fucking parent for an assclown pretending to run for office. Why am I supposed to care what this kid thinks about anything, much less the complex issues that make up politics? They're after "publicity"? For what? There's nothing interesting about them, other than that the mother needs to do a better job coaching up her seven-year-old on what to say and how to say it, and the sign is wrong. It's MAKE AMERICA GREAT AGAIN, dummy. The AGAIN is there for a REASON, dammit.
"Reality" teevee has utterly ruined what culture this country might have had, not just because of the ubiquity of it all, but because of the genre's preening insistence on taking completely mediocre people with no discernible talent whatsoever, and putting them in front of us until we know their names and faces. They are, by the current definition, famous at that point.
The best we can hope for at this point is that their scheme goes awry when mom is caught on video blowing a security guard to get into a Trump speaking engagement, and the kid ends up in -- wait for it -- public school. Yes, I would like fries with that.
