And yet somehow, it doesn't matter that these tools will be used by deeply compromised people.

US police officer Daniel Holtzclaw used his position as police officer and specifically search power to rape women. [4] It took years before the police was even willing to investigate the claims. YEARS, plural.

Who runs child services ? Pedophiles, at least in Norway [1] (and yes, that guy had used his power to get children "allocated" to him, and of course, the government decided to let that guy go, immigrant mothers however, must lose their children and get beaten up more than once in the progress. Same for the kids by the way. Why ? Well the decision was made by someone who "enjoyed child porn" for > 20 years)

The Australian police is at least partly run by criminal torturers [2] (note, aside from this happening, they also have a bit of a reputation that they're doing this, so don't think this is an isolated incident).

In the Netherlands, mental patients were thrown in solitary, and the government "can't find anyone who ever did that". [3]

In Belgium, the most notorious unsolved crime of the country, the "Brabant killers"/"Nijvel gang", famous for extremely violent attacks against supermarkets who killed almost 40 people in the process, is strongly suspected to at least partially consist of police officers, maybe entirely. [5] (one of the suspects is an ex-policeman, and the reactions of the police to the investigation defy all reason)

What is difficult to see is that, of course, positions of power attract criminals. That means a lot of criminals work for the police. A lot of paedophiles work for schools, or as priests (though not any more), and for child care, and child institutions. A lot of bullies, racists, torturers and rapists work for mental health institutions. Besides, does anyone seriously think so many paedophiles worked for the church because they liked Jesus ?

Governments don't want global thought control. Governments have police/military working for them and they pay them ... in status, in control they get over others. They want to get the criminals working for the police. That means that it's a system explicitly designed to let these people in, and the price is that the police, child care, mental health, ... bully, torture and rape.

The government can then as described in the Australia example, use this as a weapon against individuals, and they frequently do. That's why governments want to expand this power, and reduce the options people have to complain about these actions.

That's why the power of these institutions must be tightly controlled and minimized, and they must be prevented from exercising such powers without tight oversight.

The government doesn't want to do that, because that would limit their own power as well. Look at the australian case mentioned above: these laws mean that the government can just destroy individuals that are a threat or a nuisance to them. On the other hand it takes away one of the main reasons people become police officers: they want power, and of course people who want power ... use it. Here's some links to the most egregious cases.
