Sessions will implement stricter sentencing policies to reduce crime. Those policies will work and many people, including many blacks, will be happy about the new found order and safety in their community.

Then, several years from now, people will notice that that the arrest rate disproportionately affects blacks and Hispanics. The sentencing policies will be denounced as racist even though they're racially neutral on their face. The media will begin a movement to repeal the allegedly racist policies. The policies will be repealed, and crime will once again begin to rise.

Then, several years after that, there will once again be calls for law & order to get the rising crime crime under control. Repeat process.

In other words, the exact same cycle we've been on since the 60s.
