Does anyone think maybe that the present situation (as far as the situation is actually what we think it is) may be what we wanted and got? I recall is a college class on either juvenile delinquency (what an old-fashioned term) or criminology someone suggesting that if we just locked up more people, then crime would go down. That's pretty much what happened, you know, yet no one here believes crime went down, no matter what anyone says.
There are a lot of reasons crime has dropped so much, not the least of which is the high rate of incarceration in the US. Aging population, high quality of life, huge government welfare payments. All these lead to a lower crime rate. More education would help too.
