Hi all...former uni.
I do enjoy the shows, mostly as a "flight of fancy." I don't think the shows are in any way "fake." The science is real, the commitment to impartiality is real, and the process is real...most of the time. However, the shows (Miami in particular) do take certain liberties. .
1. Despite the face that Horatio is a Lt. on the MDPD, despite his excellent marksmanship, and his knack for getting at the truth, he would never be the first into a hot crime scene. Any number of uniformed/specials would go in first, followed by the lead detective, then the CSI/ESU, whatever you want to call them. Also, a CSI would not identify himself as being from the "Crime Lab," he would, in most states, be legally required to identify himself/herself as a police officer. Almost no one would know what that meant, increasing the probability of a serious confrontation (you are taught that identifying yourself as a police officer increases your control over a situation and helps to diffuse tension).
2. I have never seen a crime lab with anything other than white cinder block walls and fluorescent lighting. Maybe some anatomy posters on the wall.
3. While I think Eva, Melina, Marg and the rest are lovely women, that type of attire on a crime scene is Hollywood only. And "scruffy" Speedle would be reprimanded for his clothing choices. Most crime techs wear body suits and shoe coverings. They look more like surgeons. And any police representative out in public would wear a uniform or a tie.
4. DNA tests don't take 5 minutes. I know that's creative license for the show, I'm just pointing that out.
5. If a police department anywhere in North America had Hummers for anything other than SWAT, they would be flooded with job applications. A Chevy van is more common. When I started in 1994, crime techs drove their own cars and expensed the mileage.
6. CSIs are never left alone in a room to question a suspect. They might be present to show the detective the salient evidence. LV gets this right more than the other shows--Brass is almost always involved in the questioning, Grissom just helped tie up the loose ends.
7. The detectives in all of the shows are pretty believable. The homicide investigators I knew were always hard-working, no-nonsense people with good common sense. There were no Sonny Crocketts in Homicide. You don't get any pretense from Flack, Brass, or Tripp.
To call the show "fake" is rather misleading--it's Hollywood. It's supposed to entertain us. It's no more fake than "ER" was fake, or "MASH" for that matter. I say just let go of reality for an hour a week and enjoy yourself.
