Given the incarceration rates compared to average western standards, that's a moot point. Even if they selectively pursue, they do pursue a hell of a lot, and they do get a hell of a lot of convictions - relatively. Factor in the severity of the convictions, also much worse compared to average western standards even for the same offenses, and it's an ever worse picture.
I don't think you make anything moot by compounding more regional stats. Some countries have more crime, they underinvest in rehabilitation, addiction treatment, and social diversion programmes. Shock horror: jobless, homeless addicts commit crimes. The US also has a land border with long land borders.
That is all to say, comparing apples and margaritas doesn't do what you think it does.
In a way that matters here, I don't believe you are correct, but I cede I haven't the time or machinery to hand to prove it.
Why is convicting and sentencing criminals a bad thing?
