The crime scene and physical evidence

The most common types of physical evidence are glass, drugs, fingerprints, hair, blood, etc. It is very important because physical evidence cannot be subject to memory loss, the defendant cannot deform it, and it is a tangible object for the jury. For examination, there are presumptive tests, which are cheaper and faster, and there are specific tests, which are costly and take lots of time. In order to preserve a crime scene, the area must be secured. As for the recording, the CSI take photos, draw sketches, and take notes.

What forensic science actually is

In the T.V. shows, there are many incorrect portrayals of forensic science. They include:

1. In the shows, the evidence analysis takes minutes, but in real life, they can take hours to complete.

2. The crimes in the shows are solved in an hour, but in reality, cases can take up to a year to solve.

3. Real CSI members only perform analysis and evidence collection; they don't make arrests or perform interrogations.

4. The CSI in the shows only solve complex murders, but in real life most of the cases are accidental or natural deaths.
