How do scientists match a fingerprint to a specific person? What make fingerprints individual are the ridge characteristics. Identical fingerprints not only show the same ridge characteristics, but they also show them in the same location on the finger. Forensic scientists look for point to point comparisons to determine if the finger prints re identical. 5.
Senior Capstone in Criminal Justice: CRJS400-1303B-02 Unit 2 Group Project Individual Portion Margaret Burnett Pro. Ferguson Tire Tread Analysis Unknown tire tracks are pretty much treated the same way as footwear impressions when found at a crime scene. But, the focal point is to preserve any impressions to be later examined by forensic experts. Before they are moved or handled at a crime scene, they have to be photographed, and taken from various angles showing the visible details of the impression and its position in relation to the remainder of the crime scene. These photographs are a backup procedure because they provide a point of comparison only when analyzing the actual preserved impression.

For example, in Loftus experiments on eye witness testimony the participants were asked to say if there was broken glass present or not. This can be objectively and accurately measured and analysed The artificial and controlled environment used can be useful in ensuring other variables are not causing the effect. For example, in experiments into Jury prejudice, factors such as the nature of the crime, gender, race, and attractiveness can be kept the same or manipulated to see which is most likely to create a bias in favour or against a defendant, thus again establishing a cause and effect relationship. This environment allows standardised procedure and instructions to be applied, meaning that each participant is having the same experience, allowing accurate comparison of individual responses. For, example, when looking at the reliability of eye witness testimony, video or slides can be used to ensure each participant witnesses the same event exactly.
To answer this question, many people think that criminal profiling is solely based on race, age, and gender but it becomes much more than that. Criminal profiling involves seven long steps that include the following. First step, evaluating the criminal act itself is crucial. Specific evaluation and comprehension of the crime scene happens next. The police will then evaluate the victim such as background checks, previous crimes, maybe interviews with close relatives or friends.
The main concept behind these explications is that different races are faced with their own unique types of strains. These types of strains are economic, family related, educational, communal, and discriminatory. All of these strains have some level of interconnectivity with one another that can lead to people committing criminal acts. The reading mainly focuses on the African American and White racial groups. Even though all of these strains have an influence on the racial differences in crime, I believe that the community contributes a lot to these differences.

Some characteristics of the shoe impression are something like manufacture general outsole patterns and shapes, footwear design features and feature markings can help examiners identify the manufacturer, model and size of the footwear. This information can be used to help by placing a suspect at a crime scene. Measurements of footwear impression dimensions can be used to provide the approximate height of a suspect. With shoeprint size information, investigators can refer to
Such an approach in this case would seek to understand the attitudes of ethnic minorities towards the police through methods such as semi-structured or unstructured interviews. Unstructured interviews are informal sessions with the interviewer asking open ended questions, in this case about attitudes to the police. The idea is that respondents are free to answer in depth. However a potential problem here is that researchers could ask leading questions or put across an anti police bias, which might encourage the respondents to exaggerate their experiences. A qualitative approach ought to collect data that are high in validity.
There are chosen according to the type of research and data the social researcher hopes to find. Each can influence the data and research design in different ways.
