Where does a real csi work?
Although glamorously portrayed on TV, the majority of evidence
gathering work at crime scenes is done by officers or civilian
technicians trained in gathering and preserving evidence who then
turn it over to a centralized lab to be worked on and analyzed by
even better trained lab technicians. This is not true in ALL
departments of course but IS generally the case. Only the largest
cities and police departments can afford to support sophisticated
operations as shown by the media. In many/most cases, local
department must rely on the labs operated by their State Police
Departments or even the F.B.I. Lab.
