Pennsylvania DUI attorney Justin McShane has moved to the front of criminal defense attorneys in using forensic science to attack the state’s case. Here is a short video he produced illustrating the need to have the machine calibrated . Justin also writes a blog on forensic science issues .His commentary is on target as it concerns the Tennessee Bureau of Investigation toxicology unit .In the past , TBI has run only one blood alcohol test on all samples while good science requires two samples . Machines do need to be calibrated .
On another note , Attorney McShane has organized a training session on gas chromatography in June of this year . I am pleased to announce I have been accepted to attend the program . More in June on blood alcohol testing . I hope you find the video helpful.
