> The additional 10 years is 10 more years where they can't hurt innocent people. The justice system exists for the benefit of society and innocent citizens, not criminals.
By this logic we should just never release them. Should we keep the 80% that would not reoffend locked up to prevent the 20% that would from doing so?
Should we increase the sentence from 10 to 20 years to make that ratio 60% to 40%? Then we prevent more crime, and the would be criminals are off the street longer.
Maybe if we decrease the comfort of the cells and general state of the prisons, we can get the rate to 20% to 80%? Then we can practically say we’re justified to keep those 80% off the street.
> Why would you ever assume that? Punishments absolutely have a deterrent effect.
Because most people aren’t stopped by the deterrent effect. It’s perfectly possible the net negative effect of locking people up for a longer time is larger than the extra deterrent effect [1].

The problem with that is it removes the deterrence effect—if you're going to get the same punishment for murder as for shoplifting, criminals will exercise no restraint.

Why are you just making up numbers? The majority of violent criminals reoffend after release, often very soon after. [0]
> Because most people aren’t stopped by the deterrent effect.
Sure, most people don't commit crime because they're not morally bankrupt criminals. The point of policies is not to prevent normal people from committing crime.
Deterrence absolutely has an impact on criminal behavior. Why do criminals brazenly rob and openly deal drugs in San Francisco, but not in Miami? They know they won't be published in SF.

> Why are you just making up numbers?
I’m making a point. But numbers are more often around 20-40% in Europe.
> Deterrence absolutely has an impact on criminal behavior.
You just completely walked over the source I sent from the department of justice that said differently. Sentence length has no or minimal influence on criminal behavior.
> Why do criminals brazenly rob and openly deal drugs in San Francisco, but not in Miami?
You may notice that the same source indicates that the important factor is instead how likely you are to get caught, presumably SF police sucks at that?
