CSI is a myth compared to how the real sciences and forensic unit solve there crime. In the show CSI the murders and the crime scenes are solved really easily, and find clues and traces all most instantly. CSI always find the culprit  with the littlest amount of hair but in real life it take hours maybe even days to find DNA that is a match. Analysing the clues they find would take about a week because they have to try and match it to over millions of people. In CSI they never make false accusations but in real life when they are trying to find the culprit the could have made lots of false accusations.
