The data (linked in my comment) shows that incarceration rates have decreased in all of Europe as well as all of Northern America and increased in Australia and New Zealand.

If you consider "the West" to be (as is commonly admitted) Europe, Northern America, Australia and New Zealand (with maybe Japan included) then incarceration rates have decreased in the West. Even if they have increased in minor countries (AU + NZ).

You're getting stuck on a sentence of the summary that talks about a subset of the data, but I'm not sure why. I also have no idea what you mean about a "nation colonized to be a prison", but honestly this looks to me as if you're just trying to push some idea without vocalizing it, which is a bit off-putting. If you're talking about the US, then yes it does have a much higher incarceration rate than anywhere else in the West, but it's a clear exception within the West and it is still decreasing.
