It's complicated and depends on the place.
In countries without money or great infrastructure, often the police have just as little training and education as the US and often give in to corruption in similar ways.
In other, more wealthy countries, the police often have far more training and may generally be less corrupt and abusive because of the extensive training, but that does not mean that they are perfect nor fall prey to being controlling simply because they've been state sanctioned to be able to control.
It is to be noted that the US literally goes out of its way to choose candidates that are more likely to respond violently than not, including giving them personality tests that seek out that behavior during the initial screening process.
Mike Masnick is a good egg, which makes him valuable in times like these... Just like good eggs.
