Abstract

The concept of a criminal sign means a sign of suspicion with a concrete basis related to the particular individual. An attempt is made to collect possible crime signs through the police officer's perception and to categorize them. The procedures of this study include: collecting possible criminal signs through police officers' reports and the design of a questionnaire: collecting data on the perception of criminal signs; selecting the important criminal signs of which the averages are above a certain score; and grouping the important criminal signs which have been selected into several categories by factor analysis.<>
