When the Machine Says You’re Guilty
On a cold Chicago night, a driver is pulled over near Wrigleyville after an officer claims he rolled through a stop sign. The streets are wet, visibility is low, and he’s just leaving a friend’s birthday dinner. A few minutes later, after field sobriety tests on an uneven sidewalk, he’s at the station blowing into a breathalyzer. The result flashes: 0.11% BAC.
In the eyes of the arresting officer, and maybe even the prosecutor who will later review the case, the number tells the whole story. But Illinois law doesn’t convict people based solely on what a machine says. That number is only evidence, and like all evidence, it can be challenged.
