- Abstract
The article presents a report on various techniques used by the police personnel during investigation. In the recovery of suspicious packages by police department investigators, it is common procedure to submerge such a package in heavy oil with the idea that this oil will stop any clock mechanism if the suspected package is a time bomb. The writer believes that a word of caution is in order, namely, that the package should be examined before being moved, using a stethoscope, since, if the package contains a clock mechanism with an escape wheel, the stethoscope will probably detect the sound produced by such a clock mechanism. It should not be assumed, however, that a time bomb would only depend upon the clock mechanism to set it off. Most workers in actual crime detection work, employing instruments for the detection of deception, tend to limit their thinking as well as their technique to the conventional three indices; blood pressure recordings, respiration recordings, and some form of the electro-dermal response recording. These indices, originally the product of pure research, have proved their worth in actual police work.
