Check this article out if you are skeptical. This competition is basically sponsored by MADD.
A few excerpts from the article:
"Officers were awarded for various achievements that they have reached in the past year. Notables included Officer Josh Mallery, who made a Quakertown police record 50 DUI arrests, counting towards a third of the entire department's DUI busts last year"
"Mallery and Quakertown Officer Mario Cabrera were two of 11 police officers in Bucks County recognized by Mothers Against Drunk Driving as having the highest number of drunk driving arrests in 2007."
"MADD rewarded each officer with a tray of cookies and a certificate of appreciation. In addition, each officer received a personally signed certificate of achievement from U.S. Congressman Patrick Murphy. Cabrera made 23 DUI arrests in 2007."
