No, crime scene units are responsible for collecting and analyzing physical evidence at crime scenes. It is law enforcement agencies that investigate crimes, catch offenders, and make arrests based on the evidence collected by crime scene units.
Mostly law enforcement officers, both uniformed and detectives.
Crime Scene Investigators (CSIs) are typically civilian employees and not sworn police officers. They are trained professionals who work closely with law enforcement agencies to collect and analyze evidence from crime scenes.
