When Kyle is not in the courtroom he authors legal guides and delivers lectures to other criminal defense lawyers around the State. Kyle is published in the “Voice for the Defense” magazine published by the Texas Criminal Defense Lawyer’s Association (TCDLA) and was chosen as a lecturer for TCDLA’s Criminal Defense Lawyer’s Project.
