eradicate punishment from the law system. instead, teach.
we as a species should learn to teach right from wrong instead of simply casting away our own species into seclusion, and hoping the problem will go away.
popular law and politics dictates that we should make examples of people who commit a crime to show other people that an action shouldn't be done through means of fear.
in my opinion, fear does not work for the long-run, especially in modern times where upon the public doubts governmental law and even politicians/law-makers themselves.
i propose that methods should be developed that involve mandatory psychologists and sociologists to attend court cases with follow-ups on individuals who are jailed, periodically with the intention to develop reports on as many elements as possible that led up to the crime itself.
with privacy kept in mind, reports could then be made publicly available and delivered to current law-makers/politicians to change or remove elements of a recipe for popular crime.
in cases where societal elements themselves are part of the recipe for a crime, and can be changed or removed, politicians and law-makers have the power to do so via means of education.
to do so through schools is a start, but humans don't ever stop learning throughout their lives, so other ways of educating people who have committed a crime _and_ the public (potential crime-committers) should be made available to change or remove elements of society that lead to a crime and eventually remove the crime itself.
