Started in 2008, Model Crime Investigations (or Model CI, MCI) is a student-associated international conference. Model Crime Investigations is held annually in South Korea so it is usually known as KMCI. MCI is an extracurricular activity where students gather to learn about how a police department operates, as well as about how the broader criminal justice system functions. In the actual conference of simulation, participants will debate upon civil or criminal cases to find culprits among virtual suspects in committees. Unlike scientific investigation, in Model Crime Investigation participants usually interrogate suspects in oral arguments, and gather verbal evidence. Issues that can be discussed will vary from minor cases such as robbery to major crimes such as international terrorism. During the sessions, students who charge the investigation will have to work on affidavit by summarizing the points given by the suspects and witnesses, for the purpose of exterminating crimes by means such as arrest and/or complaint; and prosecute suspects. Along with Model United Nations, Moot Court, Mock Trial, or Model Congress, Model Crime Investigations aims to build students' global perspective.
KMCI basically follows the system of Department of Justice in United States. Committees students can take are Federal Bureau of Investigation, US Marshals, Drug Enforcement Administration, Bureau of Alcohol, Tobacco, Firearms and Explosive, or Department of Homeland Security. Each student will work as police designated as a Lieutenant, Sergeant, or Commander, or will work as suspects defending themselves as innocent. Participants (if they are suspects) will typically receive a criminal case ahead of time, which includes the facts of the crime, their roles, alibis and pieces of evidence. Students taking roles as suspects must prepare and memorize the cases given to them. During model crime investigation sessions, participants working as Police, not knowing who the actual criminal(s) is (are), must gather these pieces of evidence through investigating, interrogating and interviewing suspects in order to find out who the offender(s) is(are).
Whole committees are supervised and controlled by students role-playing as Generals:
Commissioner General, Chief Superintendent General, Senior superintendent general, Superintendent General.
| Commissioner General | Georgetown University | |
| Chief Superintendent General | Princeton University | |
| Senior Superintendent General | Georgetown University | |
| Superintendent General | New York University |
Each session is operated by students following roles as Chiefs:
Chief of Police, Deputy Chief, and Assistant Chief
Participants will be designated in the following committees randomly
And be given the roles in POLICE as
Commander, Captain, Lieutenant, Sergeant, Senior Lead Officer, Patrol Force
, OR be given the roles in SUSPECT as
Criminal, Accomplice, Witness, and so on (Types of roles are subjected to be changed according to a criminal case of committee, and participants’ role must be kept fugitive by themselves.)
Police and Suspects has different goal of their own. As mentioned above, police should find out actual offenders by summarizing evidences given by suspects. Suspects should not let police to find about who the actual criminal is. Whoever achieves their goal is to win.
By going through procedures step by step, police officers have to find out the actual criminal, or criminals. All officers shall strictly adhere to the policy of the KMCI prior to any interrogation of suspects. No coercion, threats or promises shall be used under any condition to obtain a confession, statement, or admission from any individual. The immediate objective of the interviewing officer should be to establish a cooperative relationship. To this objective, an officer should:
i. Display a sincere interest,
ii. Be patient and tactful,
iii. Be respectful
iv. Control personal feelings, and
v. Provide reassurance.
Participants can be designated as a criminal, accomplice or as a witness. They are able to lie about their positions in order to confuse police, but their evidences should match with the stances Chiefs provides several weeks before session. Suspects’ positions MUST be kept in a secret before sessions start. Actual number of criminals among suspects can vary from zero to all. Suspects making a speech, refusing interrogation or getting an interview should:
Investigation procedures are the only way which investigators can find valuable evidences. These investigations are divided into two parts: Preliminary investigation, and Follow-up investigation.
Most preliminary investigations will be conducted by the members of Patrol Force since they usually are the first to arrive at the criminal scene. All officers designated to conduct preliminary investigation shall do their utmost to gather as much information as possible during this stage of investigation since its police department's the very first stage figuring out the information of suspects. The officers responsible for a preliminary investigation shall interrogate the suspect, find out personal information about the suspect such as, but not limited to age, address, phone number, family members, and shall report the incident fully and accurately and yield the responsibility to the follow-up investigators.
Follow-up investigation will be preceded by the Senior Lead Officer, Sergeant and Lieutenant because they are usually responsible for deeper investigations. It may be possible for the patrol force to conduct follow-up investigations, but the priority is given to other class officers. In this stage of investigation, police department would try to figure out more concrete and detailed information about the offenses and the suspects as thorough as possible, including following steps, although all of the steps may not be necessary in each case: review and analyze all previous reports prepared in the preliminary phase: conduct additional interviews with suspects, and preliminary investigating officers if necessary, conduct interrogations of all suspects, plan, organize and conduct crime scene searches for the purpose of gathering additional evidences: check criminal records of potential suspects: identify and apprehend suspects and: interview apprehended suspects in order to determine involvement in other crimes.
Debate procedure incorporated UNA-USA format(United Nations Associations of United States of America) to foster active participation from students. Motions and points have to be introduced by participants to take an action in the committee, and the conference will be governed under the authority of student chiefs.
