Many of the things that lead to criminality: choosing the wrong parents, the availability of weapons, the persistence of street gangs, genetics, are things that we ultimately have little or no control over as a society. We can control how doggedly we pursue criminals, who we put into prison and how long we keep them there.
We can already see where releasing criminals will lead. "Bail reform" is a fine example. It will get many more people maimed and killed and will economically devastate some commercial centers of our country. The madness must stop.
