Four students had taken the exam. The FBI dropped voice printing, but not until it had already been admitted as evidence in dozens of courts across the country. In 1924, the first American police crime lab was created in Los Angeles, California and the Sacco and Vanzetti case publicized the popularity of microscopic comparisons of bullets used in their case. This embrace of science and charlatanism was also present in the Progressives, the ascendent political movement of the early 20th century. But more interesting were the answers the test takers gave. In 1991 development of a system known as Integrated Ballistics Identification System was put into practice with Drug Fire for automated imaging and comparison of marks left on fired bullets etc. In the early 1800s where ideas were still at large and developing an English Naturalist named Thomas Bewick used his own fingerprints to identify the books he published. So long as the defendant had a chance to cross-examine an expert witness, or to put his own expert witness on the stand, appellate courts are contented that the jury had the chance to hear both sides, even if one side is later shown or even was known at the time to have been without scientific merit.

Consequently this laid out the principles for the very first lie detection test; modern day lie detection is known as a polygraph and based on the changes in pulse rate/heart, galvanic skin response GSR (sweating), blood pressure and vast or sudden changes in the sympathetic nervous system.

It is up to the trained crime scene investigator to take advantage of every scientific and technological development inforensic investigation in order to correctly analyze, retrieve and collect evidence from the scene of any crime.
