The Texas Criminal Defense Lawyers Association and the National College for DUI Defense co-sponsored Mastering Scientific Evidence in New Orleans. LA from March 21-23, 2013.  The seminar featured presentations from some of the best DUI Defense Attorneys from around the country.  The faculty was very impressive.  I learned a lot and came back fired up to out into action so of the cutting edge DUI defense techniques I picked up.  I was honored to be invited by Mississippi DUI defense attorney extraordinaire, Victor Carmody, to participate in a break out session regarding issues pertaining to the Intoxilyzer 8000. Issues discussed included the problems with the Intoxilyzer’s flow sensor, the Intoxilyzer’s source code and unauthorized modifications done to the Intoxilyzer by drilling a hole into the Intoxilyzer’s purge valve.
