Yes, PG in political science and I have worked in policy research. How about you?
The probability of committing a crime is significantly higher if you have committed a crime before. This is constant in every society that doesn't put criminals in jail. You seem to be suggesting some interesting new theory that not having a leg is really what everyone should care about...if you were reading someone else say this would you take this seriously? No, a tiny proportion commit the majority of crime, serious crime in countries like the US is almost all committed by 1% of the population. The solution is simple: put them in jail, crime disappears.
………yes, many of them. Do you talk to real people about prison policy a lot?
> if you let them out they will commit crimes
I guess not, since we have plenty of evidence that 75yo men with one leg and cancer are at 0% risk of recidivism, and yet they’re still locked up.
