Just like there is only a small minority of bad BLM protestors causing problems, there is only a small percentage of bad police officers causing problems.
		
		
	 
I'm not so sure. There's few things more dangerous and destructive than self-richous people sure of their own goodness fighting the good fight. They tend to justify shitty behaviour with their goodness and be blind of the bullshit they do. A police officer is a hammer. It can hit things... hard. That's all they ever do. The police exist to cause problems for bad people. So they'll treat everybody they're in contact with either a person who needs to be protected or a person who is bad. Whether or not they're aware of this is another matter. But that's certainly how they behave. Their view of the world is black and white. It's all angels and demons. 
The police is a necessary evil. But it is evil. It is fundamentally evil. They can only hurt people. More or less. Usually more. 
My two cents.
		
 
		
	 
I'm pulling out this quote by you: "The police exist to cause problems for bad people." I have to say that maybe it is that way in some places in the world. Maybe in some others the police also help good people, like stop and help you in an emergency where your life or your car is having problems. But then there's also another aspect of police which is to get money. I don't know if it is like this in Sweden, but in the US, the police are budgeted locally and then some of the money police take from people is used to go to the local budget. 
In one town in the state I live, the town had a budget deficit and so the police diverted all resources to do giant speed traps and text/cell-phone usage traps and when they caught someone, they hit them with everything in the book. And they did this for weeks until the town budget was balanced.
