What's Criminal Profiling? Criminal profiling, or offender profiling, is the process of identifying the mindset and characteristics of an unknown criminal. Investigators examine the crime scene and the nature of the crime. The investigators attempt to determine the type of person the criminal is based on all the evidence and circumstances of the crime.
While DNA contains material common to all humans, some portions are unique to each individual. DNA profiling is a way of establishing identity. It is used in a variety of ways, such as establishing proof of paternity or finding out whether twins are fraternal or identical. Critics point out that DNA profiles are vulnerable to contamination errors, and invasion of privacy.
