The thirty years in which chemical testing for intoxication has had its inception and development has coincided with the thirty years in which the protection of the rights of the accused has almost obliterated the rights of our society to protect itself from persons bent on mischief. Despite this trend the courts have seen fit to encourage the advancement of the presentation of scientific evidence to enable the courts, both civil and criminal,to arrive at intelligent and just decisions. Scientific evidence,qualified by the ability and integrity of the expert, is the result of intelligent, systematized and skillful experimentation and research to discover the truth, whether it be used for or against the accused.
