Training for police and law enforcement investigators:
Investigative Statement Analysis for Patrol & First Responders
The initial interviews and statements obtained by the patrol force and first responders set the foundation for the entire investigation and paves the way for a successful outcome. If the initial information is obtained incorrectly, misread or contaminated by inappropriate questioning from the beginning, the investigation can end up being sidetracked, wasting time and money, and end up being suspended without appropriate closure. Students will learn how the words people use can be tools to effectively gather information and assess what people say, and to assist with distinguishing between truthfulness and deception as well as identifying concealed information, which is a critical skill for patrol officers! Students will improve their interview and interrogation skills as well as their ability to assess the credibility of what people say during interviews, traffic stops, neighborhood canvasses and in written statements. This day-long training provides the students with the skills necessary to secure and assess the initial information from victims, witnesses and potential suspects effectively, which will set a solid foundation and improve their investigations as well as allow for effective follow up by detectives if the cases are passed on.
Witness Interviewing for First Responders
Condensed down from our multi-day program on Cognitive Interviewing, this 1-Day training introduces patrol officers and first responders to questioning techniques used to help improve the memory of victims and witnesses of crimes. This helps the officers gather more information from people in an effective and reliable manner. Obtaining accurate and reliable information from people is crucial to any investigation, yet it is difficult to achieve, which is why nearly three quarters of people who were exonerated from crimes they didn’t commit were convicted largely based upon improper information from witnesses! Students will learn the strengths and weaknesses of human memory, and in so doing, learn techniques to maximize the strengths and minimize the weaknesses.
Foundations of BELIEF; Proper Framework for Effective Interviewing
The BELIEF Interview framework provides a structure and system for conducting thorough and effective interviews & interrogations. This full day of training will provide students with the model and structure based upon BELIEF, which stands for: B-Build Rapport & Baseline, E-Extract Initial Account, L-Listen/Look Intently, I-Identify Key Elements & Changes, E-Expand Information, and F-Follow-Up. The student’s skills will be enhanced within each of these crucial areas, and in addition, the psychology behind the BELIEF interviewing process will improve their overall effectiveness and approach to investigative interviews and criminal interrogations.
Situational Awareness/Mindfulness within Investigative Interviews
There is an attack on our attention within our current society. It seems now more than ever people are distracted, multi-tasking and being pulled in several directions at the same time. This leads to a lack of awareness of what’s happening around you, and people end up going through their day in a mindless manner, almost like being on autopilot. Unfortunately, this lack of awareness and mindlessness occurs within investigative interviews and criminal interrogations as well. The result is often missed opportunities for follow-up questioning, missing valuable information, and missing cues to truthfulness and/or deception, and in some cases, missing signs of danger. During this 1-Day training, students will learn techniques to limit distractions, improve focus and be mentally present during the interview. The skills will enhance the interviewing process and are transferable to other aspects of the student’s professional and personal life as well.
Intelligent Interviewing; Social & Emotional Intelligence within Investigative Interviews
With advancements in technology and communication aids such as email and texting, some of the fundamental skills of communication are deteriorating. It has been argued by many people that this is especially true with millennials and the younger generation, but it cuts across virtually all generations. The ability to communicate effectively, connect with people and build rapport are crucial to having strong relationships, and they are vital skills within the context of investigative interviews and criminal interrogations. This full day training program will help to develop social and emotional skills of the students which will improve their effectiveness during investigative interviews and criminal interrogation, and in general, improve their awareness and acuity in dealing with other people as well.
Investigative Statement Analysis Workshop
This is a hands-on workshop where students will be taught techniques of Investigative Statement Analysis and then work through statements and cases in detail through individual and group exercises. Some advanced principles and psychology of deception will be discussed as well. Students are encouraged (but not required) to bring their own cases and statements in to be used and analyzed during class. This course will build upon the prior training and experiences of the students as well. This course is a 1-Day workshop, but it can be expanded to multiple days as needed.
Interviewing Psychology; Deception, Persuasion and Interrogation Strategies
There are many myths regarding deception and how to tell when someone is lying. Unfortunately, when these myths get ingrained within police culture and training, investigations can get off-course. Students will learn about detecting deception, both facts and myths, and how to effectively persuade people to cooperate and tell the truth through the psychology of persuasion and influence. During this day-long training, students will also be exposed to several theories of interviewing and interrogation as well as effective tactics and strategies. We will also discuss the process of recording, documenting and other legal issues surrounding interviewing and interrogation.
Investigative Statement Analysis; Truth through what they S.A.I.D.
Knowing when people are telling the truth or lying is a critical skill for investigators, but most often their accuracy is the same as flipping a coin; roughly 50%. Academic research suggests that investigators would be more successful at detecting deception if they focused on the words people use rather than other commonly used cues, which may mislead the investigator. This training program is a comprehensive course on Investigative Statement Analysis utilizing our unique “S.A.I.D.” method, which provides the investigator with skill and ability to gather and assess information from people effectively and to distinguish between truthfulness and deception. This is applied to language that is written such as statements, transcripts, notes and memos, and orally communicated during interviews, interrogations, and 911 calls. Investigators will gain insight into the individuals thought process and obtain a powerful tactical & psychological advantage during interviews and interrogations the help them reach accurate conclusions relating to the veracity of the information people provide. This training provides proven techniques to help identify deception as well as truthfulness within language, and students will learn the psychological differences between the truthful and deceptive mindset and how stress associated with deception often manifests subconsciously within the individuals choice of words. Many times even the motive for the crime will be identified through careful analysis, which often goes undetected by investigators who have not received training in this powerful technique. This 3-Day course is hands-on and students learn through individual and group exercises with real-world cases. If you don’t know what to look for, you don’t know what you’re missing in your interviews, interrogations and statements!
BELIEF Interviewing Model
The people you talk with and interview, including victims, witnesses, informants and suspects, are going to tell you a story about what they saw, heard, or experienced. This story, along with truthfulness and deception, is communicated through language, so it makes perfect sense to have words and the content of their story to be the focus of an interview program! This, however, is NOT a statement analysis course. It is a training program that trains the interviewer to focus on verbal information and the story people provide during interviews or interrogations. It is an effective approach for face-to-face interviews and interrogations, and it is also ideal for conducting interviews over the telephone where there are no behavioral indicators to focus on, just their words. The system is based upon the acronym BELIEF, which stands for: B-Build Rapport & Baseline, E-Extract Initial Account, L-Listen/Look Intently, I-Identify Key Elements & Changes, E-Expand Information, and F-Follow-Up. The acronym BELIEF has a dual benefit as well, in that we start every interview with the belief in the person and what they have to say. The benefits of this are that it is in alignment with our core values that everyone is innocent until proven guilty, and it helps eliminate personal bias by giving people the benefit of the doubt as well and helping to prevent contamination of the interview by eliminating signals of doubt or disbelief coming from the interviewer. This approach also maximizes verbal content from the individual, and focuses the investigator on gathering, developing and testing the information obtained during the interview for truthfulness, rather than simply looking for deception. Investigators learn to base their questioning on the information provided by the individual being interviewed rather than relying on a scripted interview process or a series of steps to follow, or a rigid question & answer format. Interviewers also learn to assess the content of the individual’s account, rather than rely on their personal opinions or beliefs about the person’s behavior and/or appearance, which can be false or misleading. This narrative-based approach to interviewing provides unexpected and unpredictable questions which are difficult for the subject being interviewed to plan and prepare for, therefore helping to break any “mental scripts” the individual may have entering the interview process, which is a common tactic of deceptive individuals. This approach also allows for the implementation of tactical and strategic use of evidence as well as employing principles of cognitive interviewing and investigative statement analysis. This training course can be presented in a 3-Day or 5-Day format.
Cognitive Interviewing; Improving Witness Memory and Recall
Information from people often initiates an investigation and sets the foundation and direction for everything that follows. Information is the lifeblood of criminal investigations, yet true and accurate recall of information from people is difficult to achieve. In fact, 75% of wrongfully convicted people, convicted of crimes they didn’t commit, were based upon faulty eyewitness information! Cognitive Interviewing is an investigative interviewing technique that provides greater and more accurate recall of information from victims and witnesses of crimes. This course utilizes class instruction, group exercises and individual practice and application of the techniques, which greatly improves the ability of investigators to conduct effective information-gathering interviews. Understanding how memory works will not only allow the investigator to gather more accurate information from victims and witnesses, it will also help to identify information that is NOT coming from memory and thus, may be deceptive or unreliable. Cognitive Interviewing is one of the most highly researched methods of investigative interviewing drawing international support from the academic community as well as investigators within the field. Students will learn the strengths and weaknesses of human memory, and in so doing, learn techniques to maximize the strengths and minimize the weaknesses. This interactive 3-Day training program focuses on effective communication and powerful interviewing techniques and strategies to enhance memory and recall from victims and witnesses. This training will develop essential skills for patrol, first responders and investigators. Detectives working “cold cases” may find these skills especially helpful as memory can degrade over time. We have Cognitive Interviewing online as well through our online partners at 
Tactical Interviewing & Detecting Deception
This 3-Day training course is designed for patrol officers and detectives to provide them with a variety of tactics and techniques to set a foundation of understanding as well as practical skill enhancement relating to communication, conducting effective interviews & interrogations, detecting deception, improving witness memory and statement analysis techniques. Students will improve their ability to effectively communicate with a variety of people and personalities, build and maintain rapport and conduct effective interviews and interrogations. Students will learn questioning strategies to enhance victim and witness memory and will be introduced to key principles of statement analysis which will help them distinguish between truthfulness and deception in language. We will also shed light on some myths about lie detection and discuss what works and what doesn't when trying to detect deception and lies in other people. Students will learn how to utilize principles of persuasion & influence during interviews and interrogations in an effective and ethical manner as well as other interview and interrogation tactics and strategies, all designed to reach the truth within investigative inquiries.
Interviews of Post-Shooting and High-Stress Events
In the split-second it takes for an officer to make the decision to pull the trigger and use deadly force, a lot of information occurred leading up to, during and after the event, but will it be remembered by the officer? Will it be remembered accurately? These questions can be posed not only towards the use of deadly physical force, but it relates to conducting interviews following involvement in any high-stress situation, as the stress of such events can impact the memory and recall of facts and information. Understanding the impact of stress on memory and knowing interviewing techniques and questioning strategies that can vastly improve the accuracy and reliability of the information, which the students will learn during this training course, is central to effectively investigating these critical events. In addition to classroom training, students will experience being interviewed following stressful live-fire shooting scenarios (or paintball/Simunition, depending on the venue) and they will also utilize their training to conduct interviews of their fellow classmates who were subjected to similar stressful events. The shooting scenarios will vary and will be recorded to accurately document the event, and the interviews will be recorded as well to document the interviewing process. This will allow for the critical review and feedback for the students of both the shooting and the interview process. This course is multi-day, depending on a variety of factors.

This training will help you develop the skills and insights used by successful detectives to connect with people, extract information and evaluate the truthfulness and credibility of what they say. These aren't simply detective skills, they are people skills, and the success of you and your business will be improved or hindered by how well you can read and evaluate what people say and do.
There's Always More to the Story...
People can tell you a completely truthful story about an event and still lie to you. It is called “lying by omission” and it is one of the most common ways people lie. It’s not an outright lie where they provide you with false information, but it relates to the subtle ways people say things that makes it easy for them to deceive you, and most people don’t pick it up! The reason for this is that our brains make it easy for them to deceive us because we fill in the gaps. This half-day training will help you identify when and where people leave out information and how to effectively “fill in the blanks” whereby gathering all the necessary information so you can evaluate the credibility (of the person, HR investigation, business deal, strategic negotiation, etc.) and make sound operating decisions..
Language & Lying
This half-day program focuses on the words people say and brings to light the difference between truthful and deceptive communication. In business, you talk with people every day, but are you missing what they are really saying? Are you being lied to without knowing it? This training will help you evaluate information, whether you are communicating with your staff and business partners, negotiating a contract, listening to a sales pitch or evaluating the information from a CEO or CFO regarding a potential business merger, acquisition or investment. This training will add value to conversations and communication over telephones, conference calls and internet-based communication as well, since it is based solely on the language and words people use.
Bodies & Baselines
This half-day program focuses on body language and behavior. Our bodies communicate information, or helps to facilitate communication, with the people we connect with every day in business. This is a two-way street, so in this training we cover both aspects and students learn how to present themselves to others and how to assess other people as it relates to non-verbal communication. Sometimes the words people use conflict with or contradict what their bodies are saying. This leads to mixed-messages and poor communication, and may even be indicative of deception! You want your body and your language to carry the same message, but quite often we don’t realize there is a conflict. If we don’t realize this conflict in ourselves, we certainly will not be able to detect it in other people, leaving us open to communication problems or falling victim to deception. This training will help you understand non-verbal behavior as it relates to you and other people, improving your ability to communicate effectively and to identify potential problems, conflicts or concerns when communication with  other people so you can address them effectively.
Communicate to Connect
This half-day program focuses on communication and rapport. Communication is how business gets done, and rapport is crucial to effective communication. Rapport is not a soft skill, it is a foundational element within all effective communication. When we establish rapport with the people we communicate with in business, whether it’s with our staff and business partners, during contract negotiations or within a sales situation, trust increases. Trust is important within virtually all of our relationships, from close, personal relationships with our family and friends, to our everyday business dealings. Police detectives have to build trust and rapport with the likes of gang members, murderers and child molesters to help facilitate communication and reach the truth. These same skills and principles can be applied to improve your communication within your business dealings as well to help facilitate communication, build trust and reach positive outcomes with the people you communicate with.


Our primary purpose is to enhance the investigator's ability to develop rapport, facilitate communication, extract more accurate information, detect deception and obtain the TRUTH from every investigative inquiry.
