If the forensic labs are not doing their jobs properly, we will show that in court.

Forensics, in the form of both blood and breath testing, is a big part of a DUI case.  This is why I have dedicated myself to the study of forensic science so I can offer the best defense for my clients.  You have to know the science to hold the scientists accountable.

In my studies of analytical chemistry (the science behind the DUI tests), I have found that crime labs are not following the scientific procedures they are supposed to be following, their methods lack validity, and the efforts are not traceable  This can and does produce erroneous and unreliable results. I hold them responsible.

As most DUI defense attorneys do not know about these issues in detail, they are not able to cross-examine lab technicians and thus these technicians become lax and overconfident.  They know nobody is watching them…except for The McShane Firm.

As a leading expert in Gas Chromatography (the test used to determine blood alcohol levels) I challenge the State and their pseudo-science to hold them accountable.  The tests are only valid and reliable if the proper validated procedures are followed. I make sure that if they haven’t been followed, they are challenged in court.  Many times, this has lead to blood test evidence being ruled as not admissible or carry no weight, thus winning the case for my clients.

Every case, every judge, every jury is different. So just as in life there are no guarantees about the outcome of your case, what I can guarantee you is that we will offer you a rigorous defense and challenge the evidence all with one singular goal: to protect your rights.
