No, I mean that before, the video would've led to a closet where maybe someone was occasionally paying attention, the footage just recorded in a loop, new overwriting old, and it would only be accessed upon request when an incident happened. The matter would be handled internally; people would use their heads.
Now, surveillance can be automated and centralized. Who knows where that footage is being taken. It's no longer necessarily the school handling its matters internally. They can just offload that and accept the judgment of an algorithm. Maybe you're holding a Doritos bag and that results in police swarming you and almost killing you for fear that it was a gun.

Re: government and politics, maybe you fear your government is heading towards authoritarianism, something that would've never crossed your mind in the 00s, and that makes more conscious of surveillance. You've also become more conscious about Facebook and Palantir, etc, and how mass surveillance is a thing that's quite different from regular surveillance (handful of buildings, handled manually and autonomously).
It's not about what party. I don't think another Republican candidate would've had the same effect. Also W. Bush was on for most of the 00s; he was Republican, so what are you even talking about with parties? And though politics is a factor, I wouldn't say "When [Good Party] were in charge, they would have always done the right thing". Both ends of the spectrum can suck, and the polarity itself that's been growing in politics can be part of the problem.
