A forensic scientist is a person who goes to crime scenes and collects evidence to investigate any crime. This usually includes fingerprinting, photographing the scene, and so on. The majority of their job is done by the police in any case where they are called in, and they don’t have any other job to perform.

Forensic science is a huge field that encompasses all of the above. Forensic science isn’t the only part of forensics though. Many other parts of the field include forensic medicine, toxicology, pathology, and the like.

Forensic science includes many aspects of forensics, and the term is also used for any examination of an item that is not scientific. So while the most important part of the field is the analysis of evidence, there are also many other aspects of the field that include things like forensics laboratory, crime scene investigation, forensic anthropology, and DNA testing.

Forensic science is often thought of as science related to the crime scene investigation. Forensic medicine includes the analysis of the body, including biopsies and the like. Toxicology is the analysis of substances. Pathology is the analysis of body tissue, including blood, tissue, and fluids, and the like.

There are many, many different ways to do forensic science.

Forensic science is a very broad field of study that encompasses many different types of work, but the most common of these is the crime scene investigation. To start out, someone does a crime scene investigation, or CSI. This involves first analyzing the crime scene in order to determine what happened, and then sifting through the evidence for clues and signs to make a case against the suspect. Next, the forensics investigator goes through the evidence to analyze it for physical evidence.

And then there is the forensic DNA investigation, which is where things get interesting. Forensic DNA analysts use DNA from a lot of different people to make a DNA comparison against a sample of blood, hair, or a tissue. The DNA is then compared to a database. This allows the investigator to determine whether the DNA matches the sample, and if it doesn’t, what kind of evidence does not match.

Sure, investigators have to go through the evidence for evidence. But the forensic DNA analyst has to have all of the evidence to go through to make the decision. And that is where the fun/scary stuff begins. In the case of the DNA comparison, the results determine whether or not the DNA matches the sample. But in the case of the forensics investigator, they have to go through the evidence to make that determination.

This has been an ongoing debate for many people who are involved in forensic science. I get that there is a lot of evidence, but it’s so varied that when you have to decide between which of two samples is “real” and which is “fake” you come up with a lot of different conclusions. A good example is the FBI’s investigation of the JFK assassination.
