idk, I would say that at least in healthcare, most people are sufficiently terrified of the consequences of HIPAA violations that they won't access records they aren't supposed to. In this case, what works is a combination of serious, career-ending consequences and the knowledge that compliance departments conduct regular audits of everyone's access logs.
In Germany, there's a random audit of about 10% of queries iirc. Scandals still happen, but police officers get fired for it, and the chance of discovery and the consequences are both high enough that it's probably not as much of a problem over here.
Damn. It must be nice. Here in the US we struggle to hold police officers accountable for not shooting civilians.
I have hope that the culture around policing will change if people finally realize that the crime rates have dropped. But with fear of crime being a great lever with which to control people's vote, I don't see it happening anytime soon. The population is too vast, outliers too common, and ignorance of statistics too widespread. It will always be easy to convince people that some place they know nothing about is a Mad Max hellscape and that it's coming for them.
