Conduct Invetigations and Identification of Offenders Flashcards
For a serious crime investigation there are two team, what are they?
The investigation team and the support team.
What does the investigation team do?
Physically make enquiries to solve the case.
What are the phases and investigation is divided into for the investigation team?
Area Canvas, General Enquiries, Passive Data Generators, and Suspects and person of interest.
What does the support team do?
Provides support resources for the investigation team, to help organise and process the information gathered.
What are the two key tasks of an investigator?
- Gathering and preserving evidence, and
2. Documentation.
Investigators have to have good decision making. Appropriate and accountable decision making is based on an investigators knowledge of what?
- The legal framework
- Characteristics of crime
- National policies and procedures
Good decisions are based on a 7 step sequence, what is step 1?
Acknowledge there is a situation or problem that exists in which it is necessary to make a decision. Ask:
- What is the problem here or what will be the problem soon?
Good decisions are based on a 7 step sequence, what is step 2?
Identify, isolate, and analyse the problem clearly. Ask:
- What do I think the problem is?
- Can I state it clearly to define it to others?
- What do I already know about it?
Good decisions are based on a 7 step sequence, what is step 3?
Formulate a clear objective. Ask:
- What are we aiming to achieve?
Good decisions are based on a 7 step sequence, what is step 4?
Gather all the data and information required to determine the ways in which the aim might be achieved.
Good decisions are based on a 7 step sequence, what is step 5?
Draw up a list, based on the information, of all the possible ways in which the aim might be achieved.
Good decisions are based on a 7 step sequence, what is step 6?
Weigh and study each of the alternatives individually. Ask:
- What are the possible results or consequences of each alternative?
- What is the most appropriate means for reaching the objective?
- What are the best alternatives?
Good decisions are based on a 7 step sequence, what is step 7?
Prepare a plan for putting the selected course into action.
There are some factors an investigator needs to take into account which can affect their decision making, what are these factors?
- Individual Bias
- Verification Bias
- Availability Bias
What is Individual bias?
When an individual is unconsciously affected by their perceptions of people, places, or situations. When an individual fails to recognise the effect of their perceptions on their thinking and decision making, e.g. prejudice, diversity, criminal record.
What is Verification bias?
Verification bias occurs when thinking is channelled towards focusing on decision that support a certain point of view, thereby overlooking other alternative lines of enquiry or sources of material, e.g. a witness account that wrongfully identifies an offender.
What is Availability bias?
Availability errors occur when a person bases their decision making on material that is vivid and dramatic, emotionally charged, but it may not reflect the scope of the material available on which to make a correct decision, e.g. focusing on a victim’s account and overlooking the collection of forensic evidence.
The Appreciation technique is a cognitive tool for an investigator to take a disciplined approach to decision making. There are 4 steps to make an appreciation, what is step 1?
The Aim.
The aim or objective is a short statement of intent beginning with a verb. It should express your aim/objective clearly, concisely and in definite terms. It should be brief, to the point and there must be only one aim/objective, e.g. “To safely execute a search warrant at 123 Fake street” or “Solve the serious assault at 45 Fake Street” etc.
What is step 2 of the appreciation technique?
Factors.
A factor is a statement of truth about some known influence or circumstance.
Identify and consider the factors that will affect your aim or objective.
Examine all the information you have regarding the situation or problem. This step in the process is a risk assessment.
Identify what must be done to reduce risk and identify the resources you will require.
What are some of the possible factors you should consider?
Factors that often need to be considered in an investigation are:
- the time available
- possible suspects
- available witnesses
- material located to date
- policy and procedure required
- know history of the parties
- records that can be tapped
- the weather at the time
What should you do when you have listed all your factors?
With each factor ask yourself “So what?” i.e. what are the implications of that fact? Asking “So what?” repeatedly helps to extract all important information implied by a fact.
Keep asking that question until all possible inferences are drawn.
What is step 3 of the appreciation technique?
Courses open.
Courses open are the options you can identify after having assessed the factors and the deductions made from those factors.
There may be many courses open in any given situation, and each course must be carefully examined and evaluated.
Having examined and evaluated all the available options, each course of action must be critically examined before deciding on the most appropriate course to take to achieve the “Aim”.
What is step 4 of the appreciation technique?
Plan.
Select the most appropriate courses for attention and plan the action you can take.
Review your plan by assessing:
- Is it more then likely to be effective?
- Is is proportionate? (Effort, time, resource)
- Is it achievable?
- Will it pass the SELF test?
There are two written forms of an appreciation, what are they?
- Full appreciation
- Short appreciation
What is a full appreciation?
A full appreciation is most often for high-level or difficult tactical or administrative problems.
What is a short appreciation?
A short appreciation is used for urgent or pressing problems requiring immediate action.
The short appreciation is also helpful for non-urgent problems that are not complicated or complex.
Why should you complete a written appreciation?
A written appreciation provides a record of decision making and shows why a certain course of action was taken. A written appreciation should be completed when:
- There are several points to be considered and there is a danger of points being overlooked if they are not written down.
- A clear picture of the situation is desired to present a logical argument that will carry conviction to a higher authority.
When carrying out a short appreciation what should you write down?
In the short note form, a written appreciation need only contain sufficient detail to ensure all relevant deductions may be made from it. Therefore, the amount that is written is the result of balancing the need for brevity with the requirement to include all the data pertinent to the problem, i.e. write down key words and details to show all possible deductions have been made.
An investigative mindset means you take a disciplined approach to gathering, recording, retaining and presenting evidence. Critical to an investigative mindset is your ability to exercise what?
- Critical thinking
- Decision making
- The appreciation technique
- Evaluation
Use an investigative mindset throughout all stages of an investigation.
The investigative mindset is an attitude or state of mind that investigators adopt and develop over time. What are some of the core values that an investigative mindset should have?
Respect, integrity, and professionalism are inherent in the investigative mindset.
