content: Do you actually understand that the "best way" to limit crime is to simply kill the criminal after X number of arrests?   Something like 70% of crime is repeat offenders, the majority have multiple arrests, at some point the chance they'll reoffend is close to 100%, so if you just kill them you will definitely reduce crime. We don't do it because of how it makes us feel, as in, most of us feel it's morally wrong to take that course of action and have helped make laws and policies against it.    There's no way to be even reasonably sure that a law enforcement AI with the ability to make life and death decisions would choose the same path we have after gaining experience, or would instead take the course of action that will guarantee a reduction in crime, there's simply too many variables.
