What is what does csi stand for?

CSI stands for Crime Scene Investigation. It is a process in which forensic scientists and investigators collect and analyze evidence at the scene of a crime to determine the facts and circumstances surrounding it. CSI teams use various scientific methods to examine physical evidence such as DNA, fingerprints, hair or fibers, and ballistics to reconstruct the events leading up to a crime. The findings from a CSI investigation can be used in court to prove or disprove a suspect's guilt.
