True, although many prosecutors do also try to put their thumb on the scale when possible.

For comparison, Japan has a 99.9% conviction rate, but defers prosecution in 60% of cases. And police aren’t arresting or even attempting to enforce the law for every crime. Citizens complain that petty crime laws aren’t being enforced enough, leading to a rise in things like graffiti, litter, and traffic violations (the “bosozoku” motorcycle gangs are having a resurgence). But if you do face prosecution, there is enormous pressure to sign a confession and avoid trial, as a conviction at trial may be punished more harshly. Very similar in some respects.
