My friend dragged me to an Amnesty International meeting in college and for like the first half hour I thought they were joking. Surely... no, they're serious. There are movie villains out there in the world.
But since then I've had friends who volunteered for domestic abuse situations, and I've had a few friends who talked about former stalkers. In one case, the stalker was a LEO. My best friend's parents found asylum in the US, having snuck out of Poland sometime in the mid 80's, with the Communists hot on their trail. The Law would have had them swinging from a yard arm.
Jail isn't the solution in at least half of these cases. It's the stick being used against the victim, not a way out of the problem. In the police procedural dramas the cops have to assure people about how they're not INS, they're just here to ask about a murder. Those fictional scenarios, and the real situations that inform those writers, are essentially a case of Principle of Least Power playing out on the streets. Protests are often about changing the laws to match current or emerging public opinion. Changing a law means you're working against the law.
Consolidating all power into one place is how power trips end, but it can also be how they start. As someone else put it so plainly elsewhere in the thread, "You don't need to know" is an important concept and one we've lost. If I were President, I'd dismantle the TSA, and go back to something halfway between what we had before and where we are now. Because it looks exactly like the setup for a dystopian novel. We're still partly in the 'acclimate people to unreasonable request' but that's how totalitarians start out.
