The Krokos are a hypothetical group of people in a hypothetical society whose "membership" is assigned by the government in such a way that 90% of them have committed at least one violent crime in their lives, whereas 10% of them are innocent. Membership is assigned and revoked retroactively, the government (falsely) claims that there is a genetic component that determines whether or not one is a Kroko, and therefore, "with the improvement of new technologies, we can find out with much greater accuracy whether or not one is a Kroko". Membership is assigned and revoked with the goal of ensuring that at any given moment, 90% of the Krokos are violent criminals (i.e. they have committed at least one violent crime in their lives). For now I'm interested in the implications for the 10% of innocent Krokos, specifically the prejudices non-Krokos may have against them, the constant suspicion and discrimination they may face, how the innocent Krokos may feel about their "Kroko identity" and so on. Will they be ashamed? Will they try to be proud? Will they try (in vain) to improve the "Kroko community" to make it less criminal (even though that's literally impossible due to how the membership is assigned and revoked, the government always ensures that 90% of Krokos are violent criminals). This and much more is something I may explore.
