If you want your opinion to change things, I recommend not going into the intend.
I work in the public sector of Denmark, and we’ve increased our surveillance as much as everyone else. Often it happens after someone commits a crime. When a citizen assaulted on of our desk clerks, surveillance was stepped up to increase employee comfort. At no point during any of the pro-con discussions did anyone intentionally discuss or express any intent in terms of wanting to make our visiting citizens self-regulate. In fact the very opposite happened as it was brought up as a major concern, that we would deal with by hiding a of the additional cameras from view.
I’ve been around the top decision makers for long enough to know exactly what would happen if they happened to read something along your thoughts. They would easily dismiss it, because they in fact had the exact opposite intend.
If you want to make them listen, you need to focus much more on the result, which is exactly as you outline it. People start to self-regulate, and the negative consequences of this psychological response to being watched. Because that is the only way you’ll get your message out without people dismissing you as a conspiracy theorist or fear monger.
