In the 1960's, liberal Supreme Courts created lots of new rights for criminals and the accused. In the 1970's and 1980's, crime skyrocketed. It went up so much that even though by the 1990's the incarceration rate had quadrupled, the rise in incarceration did not even catch up with the rise in crime until 1998. On the back of that rise in crime, there was a corresponding hardening of the justice system. The war on drugs, elimination of parole, etc.

Crime has dropped dramatically since the peak in the mid-1990's. But that massive build-up of the justice system has persisted, and today the incarceration rate dramatically exceeds the crime rate. As the people who forget that New York City in the 1990's used to be Gotham City, and now only remember it as Disney Land, the political slur of "soft on crime" is going to lose some of its bite. We are seeing Obama talk about criminal justice reforms that say Bill Clinton in the 1990's never would have been able to talk about. I remember growing up in the 1990's, and all the advertisements and school assemblies about drugs--a prevailing attitude that can only be described as "hysterical." Remember Clinton having to say "I smoked but never inhaled?" Today, we're seeing legalization of marijuana all over the country. We're seeing a generation of future voters that will grow up hearing about Ferguson and Freddie Gray instead of how people high on crack cocaine are going around raping women in the inner city. That's going to change what kind of police conduct voters are willing to tolerate.
