Question about processing of homicide scenes
I’m no professional, only studied CJ but love watching crime shows.
What always strikes me in those shows is that ‘first responders’ (such as police, detectives, etc.) always enter homicide scenes, walk around to assess, etc.
I’m just wondering why the crime scenes are processed this way, befor CSI is called in?
Don’t the first responders contaminate the scene and make it more difficult for CSI to process it?
Also, why don’t they at least don some suits and shoe covers before entering, or is this just not shown in those shows?
I’m aware that smaller agencies lack separate CSI and/or other specialized units, and that detectives are trained to perform those tasks, but I’ve always found it odd that apparently, no initial precautions are being taken?
