Frequently Asked Questions
How Accurate Are the Police Procedures Shown in the Series?
I can tell you that the show's forensic accuracy and procedural realism are often compromised for entertainment value.
While they include some authentic police elements, I've noticed they take creative liberties with investigation timelines, forensic processing, and police protocols.
They'll solve complex cases unrealistically fast, and their forensic lab results appear almost instantly.
It's best to view it as entertainment rather than a true representation of police work.
