Is CSI real?

I heard someone recently say that CSI was unrealistic because it gave the SCIENTISTS on the show much more power than a real CSI would have. They said that the characters on the show not only investigate the crime scene, but they also make the arrests and even have a hand in prosecuting and sentencing, sort of like a Judge Dread character. I love CSI and I have my doubts about what this person said. Is there anyone who can shed some light on this for me?
