Gas chromatography (GC) is widely used in criminal cases whether it is to determine blood alcohol results, detect levels of drugs in the system or to identify whether or not that white powder is indeed cocaine.  Therefore, it is very important for criminal defense lawyers to be well-educated in  GC and be able to understand the science behind the test reports.

Many times, crime labs make mistakes.  Even the most sophisticated equipment cannot fully eliminate human error.  In fact, if the equipment is not maintained and calibrated properly, it can give faulty results.

The first step is unmasking GC and making sure defense lawyers understand it so they can fight for their clients.  Here is a training session I conducted in Dallas which goes into detail about GC.  If you are a lawyer or someone who has been charged with a DUI or drug offense, this is a great place to start.
