Criminalistics vs Criminology

Search For Schools

Criminalistics and criminology are two different sectors within the vast field of forensic science. They might seem similar, but the two differ significantly from one another. Criminalistics is the study of evidence to investigate crimes, and criminology is the examination of crime within society.

Criminalists collect, document, preserve, and examine the physical evidence at crime scenes. They also thoroughly survey crime scenes to detect if anything is out of place. They study the acquired evidence at a laboratory, using their knowledge of chemistry, biology, molecular biology, physics, statistics, and geology.

Upon close observation of the evidence, a criminalist must be able to piece together the events that may have transpired at a crime scene. There are many specializations in criminalistics including computer forensics, arson, blood and tissue spatter, DNA, toxicology, serology, firearms, and toolmarks, among others. Criminalists may also be called in a court of law to testify.

Criminology, on the other hand, involves the study of why crimes occur, how they can be prevented, and the effects they have on a society. Criminology uses the principles of psychology and sociology to trace the roots of crime and criminals. It also takes a look at the environmental, psychological, hereditary, and social causes of crime.

One common legal definition of criminology is as follows: “The study of the making of laws, the breaking of laws, and reactions to the breaking of laws.” By studying the socioeconomic status of a population, the areas in which they live, and the social groups of which they are part, criminologists can understand the overarching reasons for criminal activity. Criminalists also analyze the punishment and correction modes in practice and make recommendations on how crime can be reduced.

Below is a detailed comparison of criminalistics and criminology.
