Chicago Police are looking for volunteer court advocates for the July 17, 2013 court date. (It's at 9am at the 26th Street Court House.) What this means is, the police coordinate with concerned citizens who appear in court to show their support for the case. The sense is, when the community gets involved it sends a signal to the judge that this isn't "just another DUI" and helps to encourage stricter sentencing.
If you are interested in volunteering, you can contact the Chicago Police 18th District Community Policing Office at 312-742-5778.
