Peoples words will betray them. Therefore, the techniques will work with anyone who has the ability to communicate. However, if the person has poor grammar skills then some of the techniques may be difficult to use. For example, the person may use present tense verbs instead of past tense verbs not because he is being deceptive but because he does not know how to speak proper English. We have to take this into consideration when analyzing a statement. Other techniques will still work no matter what their educational level or background is.
ICB: I know that word order and certain phrases can be indicators of deception. How do issues like regional dialects and suspects who speak English as a second language change the statement analysts approach to an interview?
MM: The approach in obtaining information should be the same. However, when analyzing the statement we have to consider regional dialects or if English is not the subjects first language. The person may use a phrase that is unfamiliar to the interviewer. The interviewer will then need to ask additional questions to clarify what the person said. If English is the subjects second language, this may cause him to use the wrong pronouns. An interviewer needs to recognize this and look for other signs of deception or truthfulness.
