Interrogation can be, at times, the most important part of an investigation. If an officer did not observe the violation, has very little evidence, and witnesses are unwilling to testify, interrogation may well be the only route to successful prosecution. An interrogator may enhance his chances of success by studying and practicing interrogation techniques. The positive approach is a technique which makes it difficult for the suspect to deny knowledge of the violation as statements and questions are phrased to make it appear that his guilt has already been established. This technique also incorporates asking questions that are designed to increase the suspect's tension and to elicit verbal and non-verbal responses which are indicative of innocence or guilt. It is to the officer's and agency's benefit that we become more skilled interrogators.
