Horrible title.  The OP has fallen into the trap of describing policing as the entirety of &quot;criminal justice&quot;.  Cops are only one of many branches of the criminal justice system, one that has very little authority in comparison to courts or corrections.<p>I thought I would be reading about forensics or how technology might help corrections officers rehabilitate offenders, but instead it was about what to do with all the traffic cops if cars drive themselves ... a purely hypothetical problem atm.
