Denver was #1 on the Most Dangerously Drunk City in the country in '08 and Colorado Springs was 3rd(didn't check '09 results). Those stats include DUI's, Death from binge drinking and diseases resulting from alcohol abuse/use. Nothing involving a drunk surprises me here. I used to call DUI's in, but the cops don't do anything so why bother.
As for DPD, call the officer on the case weekly till he/she gets sick of getting calls from you. Other than that you probably won't hear anything until you get a subpoena to testify.
