Crime-rates do not correlate with police brutality and mass incarceration.
Canada locks up way fewer people, has way less harsh sentencing than the US, yet Canadian crime rates are not that different from those of the US [0].
It's also really weird to evoke HK in this discussion when the current police response in the US is way worse than anything reported out of HK. Particularly in the context that for the longest time the HK police actually had a rather splendid international reputation [1].
While US police had a "Dirty Harry" like reputation for several decades now, something that's reached its current peak with the whole "blueline" mentality and the glorification of comic vigilantes like the Punisher as a symbol for law enforcement.
As such a whole lot of this is rooted very deeply in policing and incarceration culture and not some countries being inherently "more criminal" than others.
