My client was stopped at a “road block” in Chicago. The officer smelled cannabis on my clients breath and asked him if he had been smoking marijuana. My client admitted to smoking a “joint” about three (3) hours earlier. The officer indicated that he had red and bloodshot eyes and that he had failed the field sobriety tests. I decided to go to trial. I cross-examined the officer regarding the field sobriety tests. I got him to admit that the tests he conducted on my client were more geared towards alcohol versus cannabis. I was able to prove to the judge that the officer really did not know whether my client had any cannabis in his system even tough he admitted to smoking earlier in the evening! The judge found my client not guilty of the DUI!
