Remember it well, only it wasn't just Atlanta, it was all major cities and the crime rate suddenly dropped beginning on January 1, 1993.
It was PROOF electing Clinton was a great and wonderful thing and his policies were responsible for the drop in crime.
The idiots falsifying the reports simply forgot Clinton wasn't president on January 1, 1993.
Whenever you come across a situation like this you simply have to look for the broader financial angle. If cities have a financial incentive to "reduce crime," they will under-report crime. In other circumstances, there might be a huge incentive to over-report something -- which explains why an organization like MADD reports statistics based on "alcohol-related accidents" that have nothing to do with drunk driving.
