Chicago DUI Attorney Comments on DUI Arrests

This Chicago DUI attorney has posted here and here about the Alliance Against Intoxicated Motorists (AAIM) Top DUI Cop lists.  Now the focus has shifted away from the individual officers making arrests to the number of arrests made by city by city.

From aaim1.org:

The most significant deterrents to impaired driving are law enforcement and DUI arrests.  The Alliance Against Intoxicated Motorists (AAIM) is pleased to release the results of our 21st Annual DUI Arrest Survey.
The biggest increase in arrests among the top departments was in East Peoria where DUI arrests jumped by 131.0% in 2010 compared to 2009.  According to Chief Ed Papis, “Our police department is proud to have made a notable contribution to saving lives on our roadways.  Whether they live here or are driving through town, we want everyone to know that in East Peoria we do arrest drunk drivers.”  Other municipalities with large increases from 2009 to 2010 are Chicago Heights (81.1%), Fox Lake (69.0%), Pekin (29.9%) and Springfield (19.2%).
Chicago police made 14.9 % fewer arrests in 2010 (3,695) than in 2009 (4,341), while Illinois State Police arrests increased by 7.4% in 2010 (10,734) compared to 2009 (9,996).  The sheriff’s department reporting the most DUI arrests was Cook County (515), while Lake (393), DeKalb (327), Will (267) and St. Clair (253) Counties round out the top five sheriff departments.
 Illinois State Police Trooper Daniel S. Erickson was Illinois’ Top Cop with 206 DUI arrests.  AAIM also commends the life-saving efforts of Chicago Police Officer Timothy Walter who arrested 180 drunk drivers.  “When police chiefs make it a priority to get impaired drivers off the roads, lots of arrests are made.  There are several individual officers making more DUI arrests per year than many entire police departments in Illinois.

Does anyone else think its odd that AAIM cites law enforcement and actual arrests for DUI are significant deterrents to impaired driving?
