Lie Detection
Lie detection using NLP eye movements is possible, but people are careful with their eyes if questioned. We recommend the CIA method:

The Lie Detection Process looks at non-verbal and verbal indicators
On average we can speak about 135 words per minute, we think 10 times as fast. It is generally a harder process to lie. Some forms of NLP technique can be used to make it difficult to lie. Forcing someone to stare into a bright light, asking them to remember an event backwards, and a preface of fast questions in a forceful voice can be used in the interview room to make a subject more likely to tell the truth. Forms of hypnosis can be used also.
Look for clusters within 5 seconds of asking a question. A cluster is more than one deceptive indicator that takes place within 5 seconds of asking a question. A group of 2 is not as indicative as 3 or more.
Verbal Deceptive:
Repeating the Question
Asking to Rephrase the Question
Non Answer Statements
No Direct Denial
Attacking the Questioner Change the direction of the questioning
Strange Level of Concern
Odd Level of Politeness

Memory Difficulty
Reluctance to answer the question
Referral Statements "as I said before", "as we said in our report"
Invoking Religion dress up the lie
Qualifiers(Exclusion, Perception) "basically, kind of, sort of" "honestly, candidly"
Convincing Statements(each one is considered part of the cluster) "why would I...., I care about my job"
Non Verbal Deceptive
Anchor Point Movement
Hand or Face Activity
Hiding the Face or Eyes
Grooming Gestures
Swallowing Before Answering a Question
Do not make you questions too complicated. Do not give much time between questions. Do not bluff, instead say "Would there be a reason that we found your fingerprints(or you were seen in the area)?" Always ask "What else" and at the end ask a catch all question.
