My Dad is a CSI and he hates shows like CSI and bones because they're misleading to people, he told me one time that a garda came in one day with evidence and asked it to be ready in a few days and my dad laughed at him and said "yeah, in a few weeks maybe". He hates the way they show all the work getting done instantly in the shows.
the show CSI is definitely inaccurate in what CSI actually does in real life. Most American programming make settings and scenarios inaccurate to real life stories and events. They over exaggerate things in their story telling and premises, making it more cheesy with moments that "anything can be solved and possible in real life". In CSI, the members in CSI can handle any job they can (which is pretty incorrect to what they actually do), even though they are assigned with one task.
The only Crime Drama program that made the scenarios and atmosphere almost accurate was Da Vinci's Inquest. Even if this show was made in Canada, but the vibe and settings felt so real. You have detectives doing detective work, you have scientists doing scientist work, everyone's doing their job correctly.
I guess this is what happens when you take a course of "Understanding Canadian and American Television" during college.
